Hello, Judith, I am responding to an old message.I do not have any info on Henry Rollison but I do about Henrietta Raleigh Rollison who married Samuel H. Fox in Chestertown, MD, on 17 Nov 1863. I have a copy of their marriage certificate. Henrietta was a daughter of Ludlow and Martha E. Raleigh (my family's spelling) Rollison.Samuel and Henrietta had 13 children. One of them, Margaret Rebecca, was my grandmother.She married Isaac E. Williamson and they had 6 children. Their 5th child was Margaret Elizabeth and was my mother.She married Carter Kendall in 1931. They had 3 children and I am the oldest. I have a very complete genealogy of the Ludlow family but not in MD but in VA. Sarah Ludlow married John Carter in VA and was the mother of Robert "King" Carter, who was my ancestor. I would be happy to share any info with you. Regards.
