Mary Mcdonough Rowan, Ramsey County MN and Michigan
Mary Mcdonough Rowan b. approx. 1850s married John Rowan, date unknown. They had 2 sons born in Canada, Joseph J b 1875 d 19?? and William P. Rowan b. 1881 d 19?? They eventually settled in Isabella County, Michigan.
There also may have been an older sister, Maggie Rowan born in Canada, who died in Calumet, MI in the 1890s at age 27. But I'm not sure if that was the same John and Mary Rowan.
Also possible connection to Rowans and McDonoughs in Ramsey County, MN but unable to verify.
