There has been information posted on message boards that Thomas William Cail born 1816 was the alleged father of Frederick Thurrott who was born out of wedlock in 1866,in Kent County New Brunswick ,Canada there is no documented proof to my knowledge that these statements are true, Frederick Thurrott's paternal grandson Wayne L. Thurrott has done (a 37 Y-DNA Test) as well as ( AUTOSOMAL DNA TESTS).There was only 1 male Cail surname to compare Y- DNA there was not a match. In comparing ( AUTOSOMAL DNA ) with 10 different Thomas William Cail descendants one of the descendants 3rd grandmother was the sister of Thomas Cail all of the descendants showed no shared Dna with Frederick's Dna .Frederick's paternal origins are Northwest Ireland (Ulster) according to his dna markers, some matches are with surnames O'Kane Mckeen Keane, Cain, McCain and other variant spellings,also a connection with the surname Malloy.Thomas William Cail paternal origins are supposedly (English,)Frederick's paternal origins are definitely ( Northwest Irish) ,(ULSTER) , the ethnicities of Thomas Cail and Frederick Thurrott don't match, this should resolve any doubts one may have, and that Thomas William Cail ( WAS NOT) the father of Frederick Thurrott.
