First-hand information. Entered by Timothy Martin at registration.
Both the autosomal DNA from ancestry and the Y-DNA from Familytreedna are my own and connect my paternal Martin line and the 1st 5 generations to my 2nd grandparents are shown to be correct by both websites.
It may be possible to confirm family relationships by comparing test results with Timothy or other carriers of his ancestors' Y-chromosome or mitochondrial DNA.
Y-chromosome DNA test-takers in his direct paternal line on WikiTree:
Family Tree DNA Y-DNA Test 37 markers, haplogroup R-M269, FTDNA kit #B459802
It is likely that these autosomal DNA test-takers will share DNA with Timothy:
