Chronicle of the Yerkes Family by Josiah Granville Leach published by Printed for private circulation by J.B. Lippincott, 1904
Titus Yerkes (Herman2, Anthony1), eighth son and tenth and youngest child of Herman Yerkes by his wife Elizabeth Watts, was born in the Manor of Moreland, Montgomery (formerly Philadelphia) County, Pennsylvania, circa 1731; died there in 1762, and letters of administration on his estate were granted, 13 October of that year, unto his widow, Margaret Yerkes.
He was a farmer and miller, and owned a farm of seventy acres,
since known as the "Factory Farm," located in what is now Terwood, in Moreland Township. Two streams met upon the farm, the united water- power of which was utilized by Titus Yerkes to turn his saw-mill.
He married, about 1757, Margaret Paul, who was no doubt a descendant of Joseph Paul, the founder of the well-known Paul family of Philadelphia. After the death of Mr. Yerkes she married, as second husband (license issued 4 January, 1764), John Nesmith, a miller of Moreland, and she died 16. January, 1823, in the eighty-eighth year of her age.
On 17 September, 1764, a few months after her second marriage, as the administratrix of Mr. Yerkes's estate, she presented a petition to the Orphans' Court of Philadelphia County for leave to sell the plantation and saw-mill of her late husband. Mr. Yerkes was a member of the Union Library Company of Hatboro.
