Hi Shane, Reeves is her maiden name which is why the boys were in foster care, other than the boys birth certificates we have no trace of her, she may have been married by the 1911 census, but if I could find out who her family were it would be good. I wonder if Mary could be a sister as she worked in the street where Carolines sons lived, perhaps Mary put Caroline in contact with the foster mother. She may turn up on the 1901 census, how long till its online do you know?
