I am not sure that Baruad(Bernard) was Aart son or not. Made him pretty old with his date of birth in 1799.
I do know that at least 4 brothers came from New York to Canada and than probably the 2 sisters in Nellie and Rebecca
From the Bowerman records you have Minard(Mynerdt in the New York records) who died in 1801 helping build Judah Bowermans log home. It also states he had several brothers. With the 1808 Hallowell record of land, there is 3 more in Cornelius, Aaron and Peter. Also mentioned in the Bowerman records is one of the brothers going to rest in 1826 and resting on Bowerman Hill. This is probably Corneliue as both Peter and Aaron are alive in the 1851 census. Also have 2 Johns that are born in 1791 and 92. One if probably Minards son and the other I guess is Corneliue
There was 2 Amos. The one for Baruad that was born in 1831 that married Catherine Ryan(from marriage records that list here name as this for one of the children) and another Amos born in 1821 that also married a Catherine. This one I am not sure of father but guessing it is Peter or Cornelius as the Bowerman records show Aaron and list his kids in a McDonald bible.
