Wondering if anyone can help? My Biological dad is a Dyball but im not in contact with him so need outside help, im very curious about my family tree and where i come from but i have litte info. Here's what i know...My grandparents are Bert and Joyce Dyball and they definatly had 2 sons...Mark Lee Dyball who i believe was born in Singapore at the time and another son Wayne Dyball. Im guessing the guys would have been born late 50's early 60's. Dont suppose your related to them at all?
