All of my relatives say the name is pronounced (day). Maybe some where down the line someone decided to change the pronunciation. One of my cousins' married name is Krach, pronounced (crock). However, some of her husband's distant cousins who live in a different part of the country pronounce it (crotch). So maybe this could of happened to us. The farthest I can trace the Deye name is to Penelope Deye born in 1693. She is my 7th great-grandmother. She married Col. Thomas Cockey. My relation came down through their daughter Charlotte Cockey-Deye who married Thomas Ford. Their son Thomas Cockey-Deye-Ford married his cousin Achsah Cockey and their daughter Sarah married another Cockey cousin. Penelope Deye was the maternal granddaughter of Sir Francis Thwaites Bt. She was also the mistress of Taylor's Hall in Baltimore County, as her husband died at an early age. The land at Taylor's Hall was around 1020 acres, and the building is one of the oldest in Baltimore County with the original section being built in 1670. The property was purchased by Thomas Cockey in 1725 and was an addition to many other land holdings. At his death in 1738, his total wealth was valued at over 10,000 pounds which included over 3,000 acres of land in Baltimore and Anne Arundel counties, two large plantation houses and several smaller ones, a large collection of silver, over 40 slaves and 10 indentured servants. If there is any further information your looking for on the Cockey-Deye family please let me know I would love to help.
