B E McElroy (my 1C3R)

Bertram E(Eanes according to his Military file) McElroy was the son of Andrew J McElroy and Emma Steakley.  He was at one time the postmaster of McElroy TN.  That PO was discontinued around the time of WWI and mail from then on went thru the Quebeck P.O.  He is among those in a 20 Sep 1917 article in The Tennessean whose exemption claims were denied. Bertram went on to serve in the US Army's 82 Division(Ser # 1895080) Departing 25 Apr 1918 on the ship Caronia from New York NY and listing his sister Sarah McElroy as his next of kin.  He worked as a traveling grocery salesman and as far as I know never married.  He died May 23, 1926 from a skull fracture which according to his death certificate he sustained when he was knocked down by an auto truck on May 20th.
