I am seeking any relatives of my uncle John Henry ALLEN. It would appear that he went by the name of "JACK" ALLEN. Jack was born on March 10, 1886 in Toronto Ontario, Canada, but was in Australia during or prior to WW1. In 1916, at Seymour, Jack enlisted as a trooper with the 4th, Australian Light Horse. He was killed in action in 1818. His war papers indicate that his wife was SYLVIA ALLEN. Jack and Sylvia had a daughter WILMA "Billie" ALLEN. Any information on this family would be gratefully received. George Allison California
