Oscar S. Grover was the son of James M. Grover and Margaret Putman. He was born in June 1876, at Mt. Sterling, Brown County, Illinois.
His wife Lucy Helen Burleyson was 16 when they married in Butler County, Missouri, where her mother (Elizabeth Brown) had relatives, according to my grandmother's narration.
James M. Grover, Oscar's father, was born circa 1842, also in Brown County, Illinois. He married Margaret Putman on 24 October, 1863, in Brown County, Illinois. He died the 29th of December, 1918, at Mt. Sterling, Illinois. I haven't been able to find Margaret's dod or location of burial.
