Thanks for the information.It has given me some valuable clues. It is interesting to note that all of these people were recorded on the Census with the name SWEAT butam certain that the correct spelling of the last name in at least two cases is SWEET.
In addition to Samuel O. Sweet, who was recorded as Samuel SWEAT with wife Amanda in the 1850 Census, but as Samuel O. SWEET and A. (Amanda) M. Gibson on Illinois Marriage Records,I know of Ranceller Sweet who married Rebecca Hull on Aug 19, 1849 in Pike County, ILL.per Illinois Marriage Records.The Census data you provided lists a Renceller SWEAT, 22, farmer, b. NY., with wifeRebecca, 21, b. OH, and child Mary A. SWEAT, 8-12, b. ILL.
The coincidence of having two different couples with identical first names (both husband and wife), in the same age brackets etc. named SWEET and SWEAT is too great not to suggest that a spelling error occured in one of the two records (either Census or Marriage). Since I know the correct spelling to be SWEET in the case of Samuel and believe the spelling to be SWEET in the case of Ranceller (see below), I conclude that the spelling of the name in the Census is wrong.The question then is are the other individuals named SWEAT listed in the 1850 Census for Pike County, ILL. also correctly named SWEET?
Rensselaer Sweet, the son of Ira Sweet and nephew of Job Sweet, two families that migrated to Pike County, ILL. from Rensselaer County, New York around 1838 and 1837 respectively, married a Rebeccca Hull. See Sweet Family Forum for more on thses two families.
