The Huguenots were 16th and 17th century French protestants. About 500,000 Huguenots fled France because of religious persecution. They relocated to Protestant nations.
from "Madame Mary Ferree and the Huguenots of Lancaster County"
Katharine Lefever, her oldest daughter, must have died before 1760, for in the account in her sister Jane's estate, the money is distributed to her children. In addition, Isaac Lefever, her husband, who died in 1751, makes no mention of her in his will, which is dated April 8, 1751, and proven October 8, 1751. She joined him in a deed to John Fiere on June 9, 1747, and she died probably between that date and 1751.
