Found her on the 1901 at last, that took nearly an hour! Anyway, they were living in Bow, I've already found the marriage of William and Francis, her maiden name was Jones, there is a George Jones, father-in-law living with the family. The eldest child is Frances M, year older than 6 year old Rose, the reason they were so hard to find is that they are transcribed as Garrad,
There is a link to Frances Margaret's baptism at the sdame church as Rose's baptism and i can read the address better (same one,) it is 10, Selsey Street. William's job is Engineers labourer
OO))) how lucky are you, there is a photo image of their marriage on ancestry, sept 11th 1891 Bow All Hallows, William's father was William, a brewer and Francis father George William Jones an engineers labourer, looks like william and his father in law worked together I guess
Looking at that has led me to someone oin ancestry who has them in their tree actually, hang on I'll have a shufty and see where they fit in
