Hi Henry
You need to include any of the following that you might know of that would make it easier for someone to try to help.
Any names of your greatgrand parents and grandparents, first, last, and maiden name if you have that.
Dates or approximate dates and location of their b, m, d.
Names of any of their siblings, spouses etc.
Or you could try putting what you do know in the free search tool at:
