James Dolan b. about 1792; Mary Gately

[Pat Dolan]

I would like any information on this family.
James Dolan, occupation trader, born in Roscommon about 1792. He came to Boston Massachusetts with his family in 1841.
His wife was Mary Gately, also b. about 1792.
Their known children were Ellen (aka Eleanor, 1823); Rose (aka Rosanna, 1825); John (1830); Anne (1832); and James (1837).
I'm trying to find a town or village of origin in Roscommon.
Thanks, Pat Dolan
