Some secondary sources have erroneously added "Rolly Wyatt CORBIN" as a child of our subjects, but that's a misreading of the record; he's Roland WYATT.  This enumerator included the surname for every individual on the page; he did not use dittoes or leave the surname blank.  (Note also that no son 8 yrs of age is in our subject's household in 1840.)

G Corban	58	M		Farmer	$7250	$8700	Ky

This enumerator wrote "(Wife)" for all the households where there appeared to be one.  In this case, either his wife is fibbing big-time about her age or Gamaliel has remarried or this is not his wife, it's his daughter.

Corbin, Gamlid (sic) Brethren L. & S.:--Died at his residence in Austin County Texas, on the 4th of Dec, 1870, our Brother and neighbor, Gamalid (sic) Corbin.      Bro. Corbin was born May 15th, 1802, some where in the blue grass region of Kentucky, where he has some relatives still living.  He married a Miss Miller in 1823 soon after moved down into Christian County Kentucky, lived long at the place that is now known as Newstead [Christian Co.] where he had many warm friends.  In 1852 leaving there he moved to Texas.  And in 1853 the writer of this article moved in connection with his Bro. G.I. Dabney and meeting with Bro. Corbin we bought land and settled in 1854 and 5 near together.  I then commenced talking to him on the subject of Christianity and in 1856 he was buried into Christ in baptism and became a member of the church at Sempronius in which he lived until his death.  Leaving only one child a daughter to mourn his loss.  Her mother having died some 10 or 12 years since.  Bro. Corbin fell from the platform of his gin on Wednesday the 30th of November which was the cause of his death in about 4 days...

There is a Sempronius in New York, but I can't find one in Texas.
