I'm Marcus Godfrey Stibbe's Great Grandson. My Grandmother was his daughter, Jeanette Stibbe, who died in December 1960. My mother is still alive, aged 94, and is desperate to have a photo of her Grandparents: Marcus Godfrey Stibbe and Reyna-Rebecca Stibbe ( nee Mendoza). Any leads would be appreciated. Thank you.
