This is the first time I've used Karnak and was excited to read your message concerning the Loudens. My g.g. grandfather Jacob Louden and your g-g grandfather Christian Louden were half brothers and they were married to sisters.
So far in my research I've found that Samuel C. Louden was first married to Lydia Mullis, Oct. 29, 1829 and she was the mother of Jacob, b. Jan. 20, 1836. George was born on Dec. 15, 1837, four days before his mother Lydia died.
He then married Zerelda Prowl on Nov. 9, 1838 and she was the mother of Christian.
On May 16, 1848 he married Zerelda's sister, Sarah.
His fourth wife was Frances Cordelia Boyce who he married on Feb 14, 1865.
I'm not sure where Samuel C. is buried. I have that he died on April 10, 1889 in Owen Township or Clearsprings, Jackson County, Indiana. It looks like he buried 3 wives and 10 children in his lifetime.
I have been to the Wray Cemetary where Christian and Agnes are buried. I also have a copy of your great-grandmother's obituary that was in the Lafayette Journal and Courier.
I'm very interested in any Louden information you could provide from the family Bible and would be happy to share my Louden research results with you.
