In the 1880 census for Green county, Iowa.....your Mugan family is listed as Thomas P. Magan, with wife Ann. When you look at the census image it is clearly Mugan!! It appears that Thomas' occupation was restaurant/grocer. There children are: Daniel, age 11 Micheal, age 7 Thomas A., age 4 then there is a Martin Cleary(?) age 22 living with them and listed as a boarder. He is a clerk in a store. Cheryl
