I am researching Thomason and Mims Rowena

Hi Everyone, As I understand a Roll Call, usually just surnames are used, but in the whole state of Michigan, some of us would be willing to look in our resource books for your surname, IF we knew which county your ancestors were known to be residing in, and a year. I hope I'm not out of order here. Thanks. Mary in Tx. ( Branch County, MI. researcher ) with too many surnames to try to list them.
