I'm going to keep looking for Thomas' parents. I thought you might like a copy of his obituary & picture (in case you have not seen them).
Thomas Frederick Geary was born June 7, 1822 in Philadelphia, Pa. There he grew to manhood and obtained a fair education and learned the wagon maker's trade. He was married on March 11, 1847 to Mary J. Wise. They lived happily together until March 18, 1856 when his wife died, leaving six children, the youngest dying soon after and since two others have died, leaving three sons, Charles, the youngest, being postmaster at Zora. He remained a widower until October 3, 1860, when he was married to Jane D. Morris, nee Wise, a sister of his former wife. To this union two daughters were born, Mrs. Minerva Allen and Mrs. Elizebeth R. Brown. He remained in Pennsylvania working at his trade until 1866, when he moved to Benton County, Missouri and bought what was known as the Ohaver farm and settled there. There he remained farming and kept it up until his death. He was a very industrious man, made his living by the sweat of his face, and had a competency. He was a moral orderly walking man all his life. In the early nineties he was converted and baptised into the fellowship of Big Buffalo Baptist Church of which he remained an active member. He always gave liberally to the support of the gospel and was punctual in attendance. Sometime in last April he arose early and by some means fell and dislocated his right shoulder. He seemed to be recovering until about the 5th of May, when he had a paralytic stroke of the left side and lay helpless and unable to communicate either by word or writing, but seemed to be conscious and remained in this state until 4 o'clock on Sunday morning June 3, 1900, when he passed peacefully away, surrounded by his wife, children and many friends. We cannot speak too highly of his friends for the treatment they gave him. On Monday morning his remains were followed by a long procession to Big Buffalo Church, where his funeral was preached by his pastor, Rev. A. J. Baughman of Versailles, to a large congregation of kindred and friends, after which his body was consigned to the tomb. Thus passes away a kind husband and father, a good citizen and true Christian. "But this is still a blessed sleep, from which none ever wake to weep."
