SARAH5 GORTON (William4 John3 John2 Samuel1), born Dec. 31, 1746, died March 10, 1835, married, January 4, 1770, Charles Benjamin Brown, born 1742, probably in Groton, Conn., died December 20, 1816, son of Benjamin and Deborah (Wheeler) Brown, grandson of Nathaniel, Jr., and Mary Brown, great-grandson of Nathaniel and Rhoda Brown.  Charles was Chaplain in the First Connecticut Regiment, War of the Revolution.  Nathaniel's wife, Rhoda's, family name may have been Allen.  One of her sons, Allen Brown, married, May 19, 1796, in Coventry, R.I., Mahala6Brown (Elnathan5 Samuel4 Samuel3 John2 Samuel1 Gorton).

p. 274 Image #280	855.  MAHALA6 BOWEN (Elnathan5 Samuel4 Samuel3 John2 Sam'l1), born February 16, 1773, married, May 19, 1796, Allen Brown, son of Nathaniel and Rhoda Brown, of Foster, R.I.  She died February 14, 1851; he died January 8, 1860; both in New York City.
	Mahala's maiden name was BOWEN, not BROWN, as shown in own her entry.  And if she married Allen BROWN in 1796, how can Allen (b. ca. 1769) possibly be granduncle to our subject (b. 1742)?
	If Gorton made errors as big as these, then his credibility is shot.  So... how hard do I work to support his claims for the identities of Benjamin's parents and grandparents?  Is the reason I've so far been unable to document them due to the fact that they don't exist?
