Zadock Ford ... a work in progress

Zadock Ford was reportedly a Rev. War soldier, from Maryland, whose records have been approved by the DAR. After the war, Zadock served as a justice, in the earliest courts of Spartanburg County, SC. He owned a mill and a good bit of property in the area. His will is dated 1801 and Cassandra, his wife, is said to have died Oct. 31, 1831. The names of Zadock's and Cassandra's children were given in a DAR application; and from other records we have birth dates and marriages. There is no Samuel listed, but John, born 1790 to 1800, married Sara Johnson. One reason we believe Samuel and John to be the same person is that there was a John Ford shown in an 1856, Spartanburg land dispute, among the heirs of Zadock Ford. The children of Zadock's deceased son, John, were said to be in GA, and were listed as Andrew, Jane, John, and Millie. Millie's married name, Martin, was given, and her husband, Bird Martin."

The above paragraph is from "History of Gwinnett Co., Georgia." Several documents at the Gwinnett Co. courthouse list John and Sarah. This is the only source that even mentions "Samuel." Apparently it appeared in family records.
The same researcher who gave the above information suggests either of two people as the earliest known Ford in the Gwinnett County Ford line: William Foard, seen in Prince George County, Maryland, in 1790; or James Ford, Capt., in the South Carolina Provincial Militia. James owned 150 acres in Union County, SC, and probably came from Virginia. Apparently she found no records to prove connection to either of these two men.
We have not checked the DAR application nor any of the original sources relative to the names of Zadock's children.
Another researcher, Susan Ford, believes Zadock's father was William Ford who married Jemima Callum March 17, 1751/52 in Smithfield Township, Providence, Rhode Island. She says that Zadock was born September 21, 1752, in Rhode island and died April 9, 1801 in Spartansburg, South Carolina.
Notes from Susan Ford: Zadock Ford was reportedly a Rev. War soldier, from Maryland. After the war, Zadock served as a justice, in the earliest courts of Spartanburg County, South Carolina. He owned a mill and good bit of property in the area. His will is dated 1801.

Note from Rachel Hill (rshill@mindspring.com): "There were two Zadock Fords in the Rev. War. One was from CT and married Eunice Bridges. Ours was in the 7th Co. Maryland Militia - Montgomery Co. (I do not have the war records yet.) My theory is that our Zadock is the illegitimate child of John Cook and Mary Ford. Zadock Ford was listed as "next of kin" to John Cook,Jr. along with Mary Cook (mother of John Cook) in "Abstracts of the inventories of the Prerogative Court of Maryland 1772-1774. In John Cook Sr's will his son John was disowned and left one shilling sterling. In "This was the Life" by Millard Milburn Rice (Excerpts from the Judgment Records of Frederick County, Maryland 1748-1765) is the following: "Elizabeth Boyd swears in Court that John Cook was the father of her baseborn child." somewhere I have a document that states that Mary Ford had an Illegitimate child, but the father is not named. This is all theory but I can't find anything else. Also on the list of the 7th Maryland Militia John Cook and Zadock Ford's names are together.
