My Grandmother Phylis Middleton mother of John,Ewan and Michael fostered many children at 64 Muswell Hill Place,London. amongst them one boy called Michael who was at the funeral of Phylis's son Michael Middleton and looked extremely like him. He had several brothers and sisters, a sister was fostered with him. He may not have the surname of Middleton. He would be in his mid-thirties now.
If anyone knows of him, please contact me. Thank You
