Yvette Reckert researched Benjamin Franklin Washburn for a number of years, thinking he was the son of Seth Washburn Jr. and Hannah Perkiins. She doggedly pursued this until finding the original bible of James Washburn (brother of Seth Washburn Jr.) and Susanna Raymond. This bible confirms that Benjamin Franklin Washburn is the son fo James and Susanna. Children of James and Susanna (from both the bible and a bit of info from the Woodstock, VT Congregational Church) Sukey b. 1794 Elizabeth b. 1795 Lyman b. 1798 Seth b. 1800 Phylinda b. 1802 John Raymond b. 1804 Huldah b. 1806 Benjamin Franklin b. Oct. 15, 1808 (not 1814) he married Elizabeth A. Ruth March 10, 1840 in Vernon, IL and died Feb. 23, 1863 Fayetteville, AK James Madison b. 1810.
I suggest contacting Valeria Reckert who may have a copy of the bible.I have more info., but thought you may like a copy of the source document. I believe Yvette located the bible at NEHGS.
