To try and find more of the family, if there was anymore, I looked in the 1881 British Census hoping to find Lillian and her father Henry, the engraver. What I found was very surprising. In the record below you will find that Lilian was not an only child, and in fact was one of at least 13 children living at 186 The Grove, in London, with Henry and his wife Harriett (FHL film#1341012).
In an attempt to find more on the children of Henry and Lillian, I turned to the 1911 England Census located at http://www.findmypast.com/. In that record, shown below, I was able to locate Herbert Edward Lemon and his family. His wife is listed as Annie Ida, born in Brazil.
According to the census, Herman Edward and Annie Ida had been married for 13 years. This would put their marriage date in either 1897 or 1898. Wanted to try and find the marriage date for them, I turned to the indexes of birth, marriage and death records located on line at http://www.freebmd.org.uk/. The search yielded the following information;
From this we know that Annie Ida had the surname Brandon. With the information found in the census we know that Herbert Edward married Annie Ida Brandon, who was born in 1872 in Brazil. Using that information a search was done of the 1891 Census looking for her with her family.
The records of the Lemon family can be found in The Jews of the British Isles Database.
