Hi Sandy,
My gt Grandfather was Edwin Deere, born 1851 in Penmark, Glamorgan, Wales, which is near to Bridgend. I don't know much about his siblings, but there were (are) many Deere's around the Vale of Glamorgan. My grandfather was Fred Deere and my father Cyril Edwin. Is this part of your family?
kind regards, Susanne Clift
