I'm trying to find information about the early life of my great great grandfather George Monteith. My first record of him is the 1860 census from Set Genevieve, Missouri which lists him as 47 years old (so born in 1813) and being from Pennsylvania. I have nothing before that. 1860 is also the year he married Angeline Cunningham and had three children: Joseph, Mary, and Eliza. Joseph's daughter Jesse was my grandmother. A note from her states: "George was born in Pennsylvania - tried to enlist during the civil war (in St. Louis, MO) but was rejected because of his age. When he was fifteen years of age he went to sea and was a sailor for 30 years."
I am also looking for information about when he died and where he was buried.
Any information that anyone has would be greatly appreciated.
