This may not be finding Samuel but it's wonderful to have all the new details about Lulu and Vera, thank you all and for the location of Aldershot.
Finding Vera's married name is very helpful, her death date in 1997 is also interesting as Lulu died the same year and I found them both on the Find a will Gov.UK
Vera was only ever referred to as Vera so we had no idea she had another Christian name. Charles Howard Hawes is certainly a prominent figure in their lives, he would have been, correct me if I'm wrong, a good 30 years older than either Lulu or Vera. Maybe Lulu and Vera worked for him? I wonder too where her husband was.
Thank to all your help, it's great to have more to add to a family history for Vera and Lulu. Samuel though remains a mystery!
