As you know, John Alden and Priscilla Mullins were on the Mayflower. They were shoemakers and many families claim a relationship to them including a Murphy family.
My research is also on the Doty and Cooke family.The Cookes seem to have not only been on the Mayflower but were also on Captain John Smiths boat at Jamestown. Edwin Doty was a servent on the Mayflower.
The most famious claimed descendent of the Alden Mullin line is President John Adams.This leads to Union Major Gilbert Adams Hays who by the Pittsburgh Social Register was directly related to President John Adams.
This is where I pick up the trail of Agatha Murphy, the daughter of King Louis XV of France.
It not like President John Adams would not know King Louis XV or his son.His son paid for the Revolution.
