I was given a copy of the birth of Elizabeth Jane by the family. I also found the infant death and the death of Edwin jr. in Middlesex. The family did the search so I will start with the information I am aware of...
Elizabeth Jane Davenport had siblings Mary, Annie, Alice as written on a photo. The photo/postcard taken in England of a house named Cross Trees Braemar apparently where the Davenport family lived.
Elizabeth 'Jane' lived with or was married to Walter Frederick Campbell Ramsay. They were told he was married to another woman at the time; I found another marriage if it is same man. The family believe he was from Scotland (not verified).
Elizabeth Jane and Walter had daughter (Margaretta) Margarita Elizabeth Campbell Ramsay b. 8 Nov 1897 in South Chelsea, London (birth cert), and daughter Jean Dove Campbell Ramsay. They lived on Highgate Street. Walter was a Heraldic artist.
Margaretta and Jean were sent to live with their mother's sister Mary Davenport Jones, wife of Herbet Jones.
Marg was sent to Canada with the Barnardo home children, Jean Ramsay stayed in England, married William Bonny.
British Home Children records confirm Margaretta's immigration. The sisters met again when Jean came to Canada, they were in their seventies. I understand information about their mother was shared at that time and Margaret's daughter did the search.
I don't know how Margaret's family acquired the photos of Elizabeth Jane Davenport, likely through their aunt Mary. They were told their mother left for Australia while their father returned to his family (in Scotland?)
This is confusing, Thanks everyone for your input.
