Hello! I am at the same roadblock but in Thomas (Jr) then Benjamin H. line. Have a gravestone pix w/ 1820 dod for Thomas (Sr). Thomas Sr and Abraham Rideout were patriots and their duly marked graves are in an ancient family cemetery in the Alwive area of W.K'bunk. Interesting info at Brick Store Museum too!

if you'd like. Murray Family Tree is the A.com info I've collected.
