Hi Jamie,
Yep I am a Roberts descendent on my maternal grandmothers side of the family. This is the information I have on Hiram Roberts Sr.
Hiram Roberts was born in 1830 in Northfield, Washington County, Maine. He married Mary Ann Wilbur on February 22, 1851. They're children are David Roberts born 1852, William Roberts 1854, Francis Roberts 1856, John Roberts 1858, and Hiram Roberts Jr 1864. Hiram Roberts Sr. died on May 22, 1866 in Baton Rouge Louisiana due to a contracted illness. He's buried in the Baton Rouge National Cemetary (LT I 65 USC INF, Burial plot 3 115).
As for the rest of the information. Hiram Jr. married Mary Louisa Young (Jung). They had Sadie Irene Roberts (my great grandmother. Sadie married William Grant they had Abbie Grant (my grandmother).
Thats all I got. Thanks for any help that you are able to give.
Michelle
