The surname DeBohun (de Bohon) has evolved many times and into many variations over the years. My own surname was Bone. But in this immediate area we have Bone, Bones, Bowen, Bowens, and Boone. I started noticing variations in the name around the early 1800's. It seemed at this period in time many who had come to America were not able to read or write and the name was mispelled in census records and other records quite frequently. I can give an example. I have a lady I am researching. I found the spelling of her first name as Triphena on a marriage record, as Fraphina on a census record and as Tuphena on another census record. Perhaps the census taker did not know the correct spelling or perhaps it was mistyped when it was typed for records. Whatever the reason I feel it is the same person. Her last name was Reeve before marriage in 1810, when she married Cornelius Bone (Boone?). To make it even more confusing - Cornelius went off to battle in 1815 in the Battle of New Orleans, Triphena evidently moved from Ky to Southern Indiana and remarried. It is very difficult to verify if this is one and the same person although the ages all match. The line I am researching is actually Bone but I am struggling thru the area as we live in the area where Daniel Boone and his brother Squire lived in Western Kentucky and the Southern Indiana areas. I have tried to stick with the "Bone" spelling so as not to confuse things, but it does not hurt to verify through other family members census and marriage records to make sure they all interconnect. Another cousin I had moved from Indiana to Washington area and although his parents and brothers and sisters all went by Bone - his was changed to Bones. As the family members have married or moved I have found the variations in the name change as well. My best advise would be have several sources for each person you research.
