I have hit a wall. My GGrandfather Thomas Jefferson Robertson (Robinson) was born in Franklin County in 1833. He died 1908 in Webster County Missouri. He served in the 8th Mo Calvary (Union) as a 1st Lt. He was married to Cynthia Ann Eslinger and they had 7 children. I have found only one sibling , Eliza Jane Robertson. That was in the 1860 Webster Co Mo Census. Is there anyone that can help me with this ? Thanks in advance
