I think this is the site address for the Shelton, Chilton, Skelton and Sheldon DNA test database. If you do not reach it using this address, let me and I will get the correct address from the project administration and post it to you.
Note the the test designated is from the a descendant of Ralph Shelton of Middlesex and the test designated SH-12 is from the line designated Peter Shelton. The two tests do not match. There are close to a hundred tests from the line of Ralph of Middlesex and I am not sure of the number from the line of Peter.
These DNA tests were done by the Family Tree DNA Laboratory which was, I think, the earliest genealogy DNA testing lab around.
