Have not pinned down yet. I believe we are cousins through a William Petty. I should know more later as in September I will be getting together with a cousin who has a lot of information on the Petty side. She has been contact with someone who is able to go back to early 1600's and possibly back to 1200's. They say that 90% of the Pettys came from the Sir William Petty of Britan and his son who was born in Ireland.
Keep in touch. Joyce
