As far as i know my family is not Jewish. But my grandfathers mother had him on her name, she later married and had a few more kids, but she left my granddad at her mum and as far as we know they nearly never had contact. They say my granddads father was a jewish man who was doing work with or handeling with gold in Northern Holland. So i say i am not jewish, but may be i am. I do not think there is a way to find that out is there ? Nice work you do thanks for sharing !
