The roots of this Dolan family have been traced to Ireland. However, very little is known of their Irish heritage. It appears that they settled in Saint Louis, Missouri from Ireland. I do not know when they left Ireland to come to America or where they landed. I know one family member became a judge in Chicago, Illinois.
The items below are what is available on the website for this family. Either click one of those links, or if you want to start with the top of the line, that would be Christopher Dolan
