Hello again--Your Bogart ancestors are probably related to my Vander Bogart ones. If I could ever connect my 2-great grandfather, John Vander Bogart, to any ancestors, I could tell you for sure. According to the family Bible, he was born in 1783; according to the census, he was born in Columbia County, New York. However, I think of him not as a brick wall, but as a haystack that might have a needle in it. All I have to do is go through all the records in Columbia County, and find someone with the right birth date and a name that could be his.
