My paternal grandfather was raised in Germany before coming to the US in 1907. His father was Russian and mother German. He changed his last name to Gerhardt in 1923, long before I was born. For many years I had no idea Gerhardt was not my father's original name. He told me it was Gilefski, or at least I am spelling it the way it sounded. It was an uncomfortable subject to speak to my father about, so this is about all I could get out of him. Is there a different spelling than the way I spelled it. I desperately want to search for family in Germany, but unless I can find his name correctly spelled, I don't think it will ever happen. Can someone help me!
