This may be a wild goose chase, but I suppose worth mentioning...
According to online information, Mansfield, New York was formed from Little Valley, New York
Little Valley, New York possibly formed in 1818
Online book: "History of Cattaraugus County, New York"
"Pioneer Settlers and Landholders", Little Valley
Guilson Morgan Lot 24Online book - historical gazetteer of Cattaraugus County, town of
Little ValleyGuilson Morgan, Town Clerk Years: 1824-25Asa Morgan, "commissioners of highways". Year: 1823?
Going back to the "History of Cattaraugus County, New York"
Mansfield, New York - the early settlement
Reference is made to
Amos Morgan, who someone claims was the first settler. He lived on Lot 33 in 1818 and moved to a different lot in 1825. Around 1835 he and his family moved to Northern Ohio. Mansfield's population in 1830 was 378 (not a large town). In that year, the first log house was built by Amos Morgan; he also built a framed barn (the first one built). Apparently, Amos Morgan had two sons who "became captains of steamers on Lake Erie." A Timothy Morgan was also a settler.
Could this be the same Amos as mentioned above?
1850 Orwell, Ashtabula, Ohio census
Amos Morgan, age 51, Farmer,
born ConnecticutLaura, age 55, born New Hampshire?
Samuel, age 30, Laborer, born New Hampshire? (maybe this isn't the correct family, as he should have been born in New York)
The value of his real estate was 3800.
Orwell apparently is located in Northern Ohio and down the road from Little Valley (a 2+ hour drive from Little Valley)
Could Amos have been Guilson's brother, or was it just coincidence that two Morgan men were living in (small) neighbouring towns around the same time? Was "this" Guilson the same person for whom you are looking - there's a chance that I've been looking at the wrong Guilson.
