I am doing research for a friend who is a descendant of Samuel Lewis Worms. He actually married Matilda Catherine Lyons (not Lewis) as you wrote. The marriage took place in Ceylon or Sri Lanka, then they moved to New Zealand in about 1862.
One of their children was indeed Alfred Joseph Worms born 23July 1871 in New Zealand I believe, (not Devon, England). Alfred married Mary Matilda Swinton in New Zealand,but we do not have information on any children from that marriage, except they are probably born here in New Zealand.
My friend's grandfather is , Lewis Samuel Worms, born 1868 in New Zealand (a brother of Alfred Joseph). Lewis Samuel married Kate Joanna Cox.
According to our records it was Samuel Lewis Worms who went to Ceylon, not Lewis Samuel (as you wrote).
My friend is interested in exchanging information. In particular she wishes to identify the parents of Samuel Lewis Worms. We have possibilities, but nothing proven.
