Solomon Longsworth was born in Maryland or Virginia, probably between 1750 and 1760. He was involved in many land transactions in Maryland's Baltimore and Frederick Counties and he appears in the 1790 and 1810 censuses of Frederick County. He and his wife Lucretia (Lucy) Nelson raised a large family, most of whom moved to Ohio. Many, perhaps most present day Longsworths are descended from Solomon and Lucy.
This web site is based on a Longsworth genealogy: Longsworth Family History, by Mary Longsworth Breese; Lima, Ohio; 1951. All of the Longsworths who appear in Mrs. Breese's genealogy are included in this web site, though other descendants and much personal information are omitted. Her genealogy is a typescript, available on microfilm through Family History Centers.
My intent is to add information, particularly about the earliest generations, and to bring the site up to date. If you would like to contribute information or correct any errors, I'd be very pleased to hear from you!
