There were three Benjamin Willsons That I know of While I'm no expert here is what I have Benjamin Sr. Born 1670 In Woburn Mass. Son of John Fuller and Hannah James. Hannah married late in life Thomas Fuller 1688. Benjamin Sr. married Elizabeth Fuller Thomas Daughter?.They had Benjamin Jr. Can't think of Benjamin 1st wife Second wife was Elizabeth Sprauge Mayflower decendent of Richard Warren.They had Seven Children John,lucas,Ammi,Benjamin #3, Jonathon, Ezikiel,and Chloe,like to here if you think there the same Benjamin. There is alot of confusion on Benjamin Willson keep in mind there a least 3 maybe 4 with yours. Good searching Michael.
