My ggg-Grandfather Elisha Alden had a daughter named Rosetta b.1840's? in MA., they moved to MN from Canada and resided in St. Joseph near St. Cloud in the 1850's. The family later moved to Colorado and Rosetta isn't listed with the others in the CO. 1870's census. So could be your Rosetta. E-mail me at email@example.com and can give you more info. on this family.
