Am watching the roll call for the Arbuckles or McCoys. James and Isabella McCoy are buried in the Browning Cemetery east of Denver IL. I have such a very strong suspicion that Isabella is a sister of my gggrandmother, Margaret Clark. Both women were from Ireland, had the maiden name of Arbuckle and their birth dates are such that they could have been sisters. Margaret was born in 1798 and Isabella in 1790. Is there anyone with Arbuckle or McCoy genealogy that we might compare? I have found the name of Archibald Arbuckle as the father of Margaret. If only we could find a census that would provide the names of his children!
