I wish I could be of some help, but David Washburn is a bit of mystery. I have not yet seen any document that connects him to any other member of the Washburn family in any capacity. I can not even identify him as any D., David, or Daniel Washburn who is head of a household in the 1810 census. [ The names David and Daniel are often confused in the records] In fact since he was probably recently married there is no guarantee that he WAS a head of household. He could have been living in the household of his father, his in-laws, his brother, her brother etc. You can suppose that the children are named after relations, but I don't want to go that route without some tangible proof of a relationship with the Washburn family. Lots of families had children named Isaiah and Samuel. I haven't yet seen a record where David Washburn bought land and perhaps had a brother as a witness. I haven't seen any probate records where a Washburn gives anything to the children of my deceased son/brother David Washburn. The David Washburn/Washbon that I find of this time period are still living in 1820 which effectively eliminates them as being the David Washburn we are looking for. They are each in entirely different Washburn branches of this family so I can't even use naming patterns as a source of clues. If I see anything that looks like it is a clue for this branch I will post it to the Washburn board. Sorry I can't be of more help. Susan BIngler Fairfax, VA
