Sara- Yes, I am also related to Joseph Carroll (gggrandfather). Someone in my family did work on this this tree years ago, but only made it back to the late 1700s. Joseph's father was named Ignatius Carroll (from St. Mary's) and his mother was Julia Bridget. His grandfather was also named Ignatius Carroll and his grandmother was Winifred Coates. Our family has always insisted that we were related to the Carrolls of Carrollton, but I am still unable to establish this link. My guess is that this line of Carrolls came into the colonies through Saint Mary's port. Do you have any other information?
