See Lynn Jackson's summary of the Morgan family at http://www.lynncjackson.com/family/morgan.htm

John Morgan

Per the census records, John Morgan was born sometime between 1804-1816 in Delaware. It is not clear how he was related to James Morgan or William Morgan but they were all members of the same Kent Co. mixed blood community and of the right age to have been brothers.

By 1840, John was married with 4 children. Among these was Catherine Morgan . We know nothing about John's wife, although Catherine's daughter, Annie, told Weslager that Catherine's mother was a white woman.

DNA testing by Catherine's 2great-granddaughter, Betty Terry, confirmed that the mitochondrial DNA in the female line is indictative of Northern European ancestry.

William H. Morgan

William H. Morgan was born in Kent Co., DE on 16 Dec 1807. His relationship to John Morgan and James Morgan is not yet known but they were possibly brothers.

Samuel Morgan

From the pension record of John Hughes, Private, Company K, 1st District of Columbia Infantry, also known as 1st U.S. Colored Infantry:

John H. Morgan stated in an affidavit dated 19 Nov 1913 that his uncle Samuel Morgan had married Elizabeth Cork, an older sister of Deborah Cork Hughes. He stated this marriage took place a few years prior to the marriage of John Hughes and Deborah Cork.

From Joseph Romeo: this entry from the 1850 census may relate:

1850 census, Delaware, Kent County, Little Creek Hundred, [page 69]:

Samuel Morgan, 30, Male, Mulatto, Laborer, b DE
Mary, 25, Female, Mu, b DE
Saml, 10, Male, Mu, b DE

From the deposition, one infers then that Samuel Morgan, b. ca. 1820, is a younger brother of William Morgan, b. ca. 1804, who in turn was the father of John H. Morgan.

The name Mary in the census record does not match the name Elizabeth given in the deposition, unless her full name was Mary Elizabeth.

James H. Morgan

(from Lynn Jackson's web site, Moors & Nanticokes)

Based on the census records, James Morgan was born in DE sometime around 1821. His relationship to John Morgan and William Morgan is not clear but they were all from the same mixed blood community in Kent Co. and all of the correct age to be brothers.
