I hat e to tell you this but your assumption on Thomas Hammond was wrong. Thomas Hammond who married Anne Cockey was the son of John Hammond and Anne Greenbury. Sorry.
Good thinking though. If the Hammonds are anything like the Cockeys, they keep using the same given names over and over again. For instance there are about 10 Joshua Cockeys alive today in Baltimore County.
Let see where I last left off. Oh Yes! Charlotte Cockey-Deye, the daughter of Col. Thomas Cockey and Penelope Deye was born 2 June 1724. She married Thomas Ford, who was a vestryman at St Thomas' Church near Garrison Forest in Baltimore County, on 19 March 1740. Unfortunetly I do not have any more information on them other then they did have several children, however the only one I know of was their eldest son Thomas Cockey-Deye-Ford. It was he who married his 2nd cousin Achsah Cockey.
Thomas Cockey, son of Cpt John Cockey and Elizabeth Slade was born at the family plantation in Green Spring Valley in 1724. He settled on his lands,willed to him by his uncle,at Garrison Forest in 1753. In that year he also married his wife, Prudence Gill. They had 8 children; Thomas 1754,Achsah 1755,Elizabeth 1757,John 1758,Anne 1760,Charles 1762,Stephen 1764 and Caleb 1766. Thomas owned many tracts of land in both Anne Arundel and Baltimore. He was styled as a Thomas Cockey of Baltimore County Gent., standing for gentleman, which was noble status to achieve in those days and not taken for granted as it is today. He died in 1784. His will indicated a rift that had arose with his eldest son, Thomas. Apparently he was distraught over his sons' loyalist activities during the Revolution, as he left his son only "one shilling and it is my desire that he never enjoy any portion of my estate by the death of any of my children". We are descended from two of Thomas's children, Achsah and John. John being the eldest son after his "unfaithful" brother recieved the bulk of his father's landed estate. Achsah recieved as did her other sisters 100 pounds. Their brother Stephen, died shortly after without heirs and divided his estate to his siblings and nephews. John received much of his brothers landed estate including the last of the families property in Anne Arundel County. Achsah did not do without, as she was deeded Sewell's Hope, Fool's Folly and Sewell's Contrivance of over 300 acres, by all of her brothers in 1787.
