Do you have any info on this family? Isaac Bolmer(1), b.abt 1790 & wife were in Warren Co, Ohio in the 1840 Census. They had 2 sons living with them. Also, another Isaac Bolmer(2), b. Jul 1811 in Newark,NJ,along with another male near his age, was in the same area. I believe these men are Isaac's sons:Isaac(2),Abraham,John L,& Jacob.
