Re: Kenneth Allen Hadley, 1931 - 2001
Wife and kids, no. You might find something in his obituary. Ethical genelogists don't post details about living people in public.
Ancestors - I could undoubtedly work for 30 - 40 hours fleshing out the leads I gave you, following the siblings to see who they married, and going back to 1850, but I tend to answer specific questions, not to do "Ancestors of" reports.
