I have quite a bit of information on the Peckham line.William Thomas was born in 1804 in Jefferson Co., OH and died 8-18-1881 in Bloom City, WI.He and his wife Mathilda Maple had 5 children.
William's father Charles Wesley Peckham was born 11-13-1767 in Middletown, Newport, RI and died 2-15-1861 in Salineville, Ohio.He was married to Rhoda who was born 1-29-1769 but last name is unknown.
Charles's father was Joseph Peckham born 5-2-1738 in Middletown, Newport, RI and died 7-12-1812.He was married to Sarah Weeden born abt. 1742.
If this is the correct family and you need more info let me know.I would also be interested in what you have since you indicate you have the family back a long way.I have it to George in 1449 but the info gets a little sketchy. Vonda
