Have you heard of William Thomas March?

A Jamaican-born naturalist and collector who made enormous contributions to our understanding of the natural world.

This Black History Month I was invited to write a guest blogpost about my research on William Thomas March (pictured below). A published Jamaican naturalist and collector from Victorian times, March contributed over 1,400 specimens to museums worldwide.

By researching March’s collections and locating which museums house them I hope to help update the face of Victorian collectors to include more people of colour.

Advisory Note

This blog contains a direct quote from the 19th century that includes a term for individuals or groups that are reflective of certain racist ideologies of the period. We include this term, offensive by today's values, exclusively in the historic context in which March's story is set.

Who was William Thomas March?

William Thomas March (1804 – 1872) was a ‘free man of colour’ born in St. Catherine, Spanish Town, Jamaica. He was a privileged man of colour and achieved many milestones. Between 1837 and 1854 he held titles of attorney at law, member of the House of Assembly for St. Catherine, Treasurer of Beckford’s Free School, Trustee of the Spanish Town Savings Bank, and Vestryman in St. Catherine.  

March went on to become the Deputy Clerk and then a Clerk of the Supreme Court. He was also the Island Secretary/Secretary to the Governor of Jamaica from 1868 to 1872 and a member of the Council of the Royal Society of Arts in Jamaica. 

March had a mixed heritage descending from black and privileged white family members. His white paternal grandfather passed ‘An Act to entitle his children [birthed] by Elizabeth Rogers, a free Mulatto, to the same rights and privileges with English subjects born of white parents’ (UCL Dept. History 2023). This Act almost certainly helped March’s life and status as a free man of colour compared to other less privileged Jamaicans with black ancestry who were discriminated against during this time.

March and Kew - a shared history 

Whilst researching collector’s names and their ethnicities in the zoology collection records at World Museum Liverpool, I came across March’s name and decided to research further.  

To date, I have found that March contributed over 1,060 specimens to Jamaican zoology collections around the world. I also found that he collected thousands of botanical specimens with many sent to Sir William Jackson Hooker (Director of RBG Kew, 1841-1865).  

The two men frequently corresponded through letters between 1853-1860. March shared his knowledge of the flora of Jamaica with Hooker and sent around 2,000 plant packets, samples and seeds to him at Kew. In return, Hooker sent plant packets to March for him to grow in Jamaica and conversed on all things botanical. Sadly, not all the plants that they sent to each other survived the treacherous sea voyages, which could explain discrepancies in specimen numbers.

Aside from March’s day job, he collected many zoological and botanical specimens for naturalists in England and America as a hobby. He found himself within a network of well-known naturalists during this time. He sent specimens to Charles Darwin, Sir William Jackson Hooker, Nathaniel Wilson, Spencer Fullerton Baird of the Smithsonian Institution, WA, USA and many more naturalists.  

Spencer Fullerton Baird (1823-1882), first curator of the National Museum at the Smithsonian Institution, honoured March’s work by naming a small bird native to the Caribbean and South America - the black-faced grassquit Melanospiza bicolor marchii - after him. He said March had “done so much towards extending our knowledge of the natural history of his island.”.  

Indeed, March was a pioneer in providing some of the first biological data available for the Caribbean with his exceptional knowledge as a local resident naturalist. His collection of type specimens (a specimen used to describe a species) and specimens of now extinct species continue to help researchers who focus on Caribbean biodiversity, and the specimens continue to provide historical data for these scientists today.

That’s not my name 

One of the key difficulties in researching March’s collections is the constant misspelling of his name in records. Specimens are often labelled as W.J. Marsh, W. (T.) Marsh, W. E. Marsh, W. L. Marsh, W.W. Marsh or simply Mr. Marsh, but all correlate to the times and places where March was collecting.  

Through my research on March, I connected with some of his present-day relatives. They told me, it was common for the name March to be spelled Marsh either due to the spelling at the time or because ‘March’ may have been pronounced ‘Marsh’ based on different accents.

March’s ambition 

March proposed the idea of launching his own botanical magazine in England, complete with coloured plates created by a Jamaican lithographer, Miss Catherine Eloise Dubuisson, who visited Hooker and Kew in 1857.  

Another project, which Sir William Jackson Hooker agreed to assist with was March’s handbook of [Jamaican] ferns. March was encouraged by his friends to publish the handbook, as detailed in letters from 1861. But it is not clear whether these projects were fulfilled.

March’s collection at Kew 

This summer I visited Kew and was given access to the Herbarium collection and March’s specimens.  

His collection was fascinating to see in person as even after over 200 years many of the herbarium sheets had well preserved plant pigments, as well as little handwritten notes stuck to them. It was also incredible to see March’s spirit specimens of Wild Sweet Sop, Fruits of Wild Mammee, Spanish Plum and more. 

The genus that stood out the most for me were the water lilies (Nymphaea) because they were so distinct and recognisable. These herbarium sheets were the last in the box – so I ended the day on a good note.  

I was also fortunate to have a slot booked in the Kew Library and Archive to look through material associated with March. This consisted of many letters and ‘Goods Inwards’ books documenting the specimens and their condition that March sent to Kew from Jamaica.

A legacy for March and others 

It’s important that contributions, similar to those made by March are given a permanent place in museums to promote and explore positive black histories, and share stories with visitors on the many faces of collecting. This can help to change the ‘norm’.  

It’s equally important to note that local people around the world were not always ‘helpers’ or ‘navigators’. Some, like March, were well-educated collectors, with impressive day jobs, and were highly respected amongst their white European peers. Telling these stories in our heritage institutions creates a more inclusive environment where people of colour can see themselves represented and championed as part of major scientific collections.  

As the digitisation projects of collections progress, I am hopeful that more March specimens will be uncovered.  

The specimens and archival material that Kew’s staff – Edie, Gayathri, Melissa and Isabel – located for me were fascinating. I’d like to thank them for their help and insight into historical botanical collecting practices.
