In my research today I came across an Emmaretta Lefevre born in Rotherhithe, London in 1864. She is the eldest of four children of John Henry Lefevre and Emma Wilsdon. It is an unusual first name that I have not come across before but doing a search on FreeBMD turned up 71 girls of that first name between 1837 and 1905 but none post 1905.
Another thing of interest about Emmaretta is that on 27th December 1906 she married Frank Lefevre Coard. Frank was born in Hackney in 1863 the son of John Coard and Ellen Lefevre. Frank must have taken his middle name from his mothers’ surname. I now need to see if I can find any relationship between John Henry Lefevre and Ellen Lefevre.
