I'm trying to establish who Cobus Vanloan/Vanloon is, there is no record of him. What is known is that Cobus married Debra Allen before 1800. They lived in Conesville NY. Debra was living with son her Jacob according to 1850 census. I think Cobus is nickname for James Vanloan however my theory needs to be validated. Any information is greatly appreciated to link Debra with the first name of her husband.
