I am not researching McGUIREs. I just checked the 1850 census for you and did not see a McGUIRE family with a young daughter named Margaret or Mary. Suggest you try the 1860 census of Morgan Co. kandice wrote: > Hello, > I've just received the marriage certificate for my ggreat grandmother which > states her mother Margaret "Mary" Mcguire was born in Morgan County abt. > 1850. Is anyone on the list researching the Mcguires of Morgan County?
