I have a Lucy Rowell who married John Leavitt. They made the journey from Hatley Quebec Canada to Salt Lake City with stops at the Mormon enclaves in Kirkland OH, Twelve Mile Grove IL, Winter Quarters NE. They left Hatley in 1837 and arrived in Salt Lake in ca 1852. She had a Brother, Thomas Jr. who married John's sister, Lydia. She had a sister Sarah, who married John's brother, William. They were all Mormons who made the same journey.
I also have a Phoebe Rowell who is the daughter of Thomas. She married Samuel Wadleigh from Hatley and lived for a time in Oquawka, IL where he was a successful merchant and later they moved to Burlington IA where he became even more successful.
They dates are all consistant, but the question is, "Is this all one family, Father Thomas, siblings Lucy, Thomas Jr., Sarah, Phoebe?"
