Hjalmar Ekerholm was born March 21, 1886; died September 1974 in Europe. He married Augusta Katherine Wass (born August 6, 1889 in Mankato, Minnesota and died January 19, 1940). Hjalmar Ekerholm's father was Wilhelm Ekerholm. Wilhelm had two children as far as I know.. Hjalmar and Oscar William Ekerholm (my great grandfather). I can't get past Wilhelm. This is the first time I have heard of Erik Ekerholm.
