I have found a little bit about your Lee Pierce. On the 1920, 1930, and 1940 census' he was in Honolulu. He apparently arrived there a few years earlier because about 1913-14 he married Ivy (maiden name ??) in Honolulu and they had at least 2 children by 1940. The children were Eleanor (born 1915) and Sybil (b. late 1916). They probably had more children in the 1920's.
Ivy was born 1/16/1888 in Honolulu and died 9/30/1975 there. Lee was born 4/15/1880 and died 1/16/1968 in Honolulu. On the 1920 census he indicated he was born in Missouri, his father in Ind. and mother in Mo. I don't know where he was born in Missouri or his fathers name.
Both Lee and Ivy are buried in the National Memorial Cemetery of Pacific in Honolulu. Thatis where US Army soldiers are buried.Sorry I did not find more. Bob Eddings
