Hi Robyn

There's a tree on Ancestry which was submitted by a granddaughter of Jessie's son, Gordon Maxted. Perhaps it's your own tree, but if not, then one of your cousins has submitted it, and you could contact her using the Ancestry message service to see what she already knows. She's got lots of siblings for Jessie, and also Jessie's parents plus names for 3 of her grandparents.

Hope this helps
