Judith Hamilton has always been a confusing situation. That is because no one has been able to locate the parents of the second Judith Hamilton. My father was the author of "Our Calhoun Family". On page XIX and XX at the front of Volume 1, there is a family lineage of the Hamilton and Calhoun families. Sir James Hamilton only had 1 son, and two daughters, Sidney & Judith. Judith's son Audley met another Judith Hamilton and married her but there has been no information on her family. Are you researching the Hamilton family lineage? You should go on the Hamilton site and there may be someone there who has information that you are looking for.
