Hi,
I am Fred Drost oldest son Darrell. Yes many people called him Sonny in my younger years. Dad pasted on 5 Feb 1979 (30 years ago) We visited his sister Mickey in Iowa in 1978 I beleive, I was 15. His other sisters are Kay and Lucille. Lucille is passed, not sure about Kay. His half sister Jody (Geneva) still lives in Caribou. My mother (Aline)sister (Gail) brothers (Scott, Edward (Eddie) Andrew (Andy) all still live in Caribou area. I live in Texas. My mother would know more about your Grandmother Geneva who is also passed away. My email is rufsnowL at hotmail dot com. maybe i can provide more info.
