descent.
A new bloodline has been recently traced to when the Dempseys came to America. When the family known as the Dempseys got off the boat, they were asked their legal names by American officials, who would put them in the American records, making them a citizen, it was misspelled Dimsey, therefore creating the Dimsey bloodline. Another group of the family came on the boat, and was correctly identified as Dempsey, leading to the American Dempsey bloodline. Similarly, Dempcy dating back to the Revolutionary War, was also a misspelling of Dempsey.
