I've been researching some family history for my parents. There is a family legend regarding my great-great-great-Grandmother being a lady in waiting to Queen Victoria. I honestly didn't buy believe it but while doing research I discovered some facts that made it slightly more plausible. I did, in fact, search for some sources listing all her ladies in waiting but the only sources I found were self-described as incomplete. It's also possible that she was not a lady in waiting per se but a different position in the royal household.
Here is what I do know. He name was Ada Kettleborrow and she was from Bottesford, Leicestershire. Her family was well-to-do but non-noble and were listed in the local records as one of the largest land-owning families in the county after the Manners (the Dukes of Rutland) and a couple of other families. In 1890 she married Valentine Green (not the artist), the son of John Green, the steward of the Duke of Rutland. John Green had been steward at Belvoir Castle since 1840 and political agent to His Grace Charles Cecil John Manners, 6th Duke of Rutland and Marquess of Granby and onetime Lord of the Bedchamber to Prince Albert. After learning all this (thanks to some published histories and reading many issues of the Grantham Journal), I realized it might be possible that she served as a lady in waiting or some similar function in the royal household.
Does anyone know if there is a fully listing of the servants in the Royal Household or if it would even have been permitted for the daughter of a non-peer to serve in the royal household in this fashion? It seems unlikely she would have been a maid given her family's fortune and station (though I can't say for certain) but could she have been a lady in waiting and is there a way to find out for sure?
Queen Victoria's Ladies in Waiting and Ladies/Mistresses of the Bedchamber were all titled women - actual Ladies, and some Duchesses. However, there were such attending positions as Women of the Bedchamber and Maids of Honor which would be held by non-peers. This is maid in the sense of "unmarried woman," as opposed to housemaid. When I say non-peers though, I mean women who don't have their own titles, but not women who aren't closely related to peers. When speaking of the Queen's household, these are going to be the daughters of lesser peers, the wives of heirs who are soon to inherit, and similar.
In any case, the best reference I can point you towards is "The Royal Household" written by William Alexander Lindsay in 1898. It contains a complete account of every person who waited on Victoria from 1837-1897, their positions, salaries, etc. You'll note there's a 3 year gap here at the end of her reign. Some appointments were published in the London Gazette if you'd like to try to pin down the missing years. I couldn't find a ready digital scan of The Royal Household, so you may need to go to your library for help accessing a copy. This page claims to contain a complete list of all of the female attendants, including the ones appointed after 1897, but it does not include the entire staff. If Ada Kettleborrow/Green was present in some other capacity, she might be in the book. She does not appear to be on the list of attendants, though. Sorry about that.
