Hello. I am researching a Joseph Tinker that served in the 27th Iowa Infantry during the Civil War. I know he was from Clayton County, but know little more than that. Can you tell me if you have any information regarding a L. H. Tinker and Mary Tinker that is in connection to Joseph Tinker. I'm thinking perhaps Mary was his sister and "L. H." his wife, but I am unsure. Any info you can share would be greatly appreciated. Thank you.
