From the book by Thomas Fortescue Lord Clermont "A History of The Family of Fortescue in all its Branches" published in 1869 and 1880 and on page 135 he writes.
"Hugh Fortescue, whose will is dated January 5 1714, died in 1719, and was succeeded by his eldest son Hugh, born in 1695; who in consequence of the death, without issue of Edward, thirteenth Baron Clinton, and fifth Earl of Lincoln, obtained that ancient Barony, which, on the 16th March, 1721, was called out of abeyance into which it had fallen in the year 1692, by a writ of summons to him as fourteenth baron, in the right of his mother Bridget Boscawen only child of Lady Margaret Clinton, youngest daughter of Theophilus, twelfth Baron Clinton and fourth Earl of Lincoln."
Seymour Fortescue published in 1920 a book "Looking Back" and he talks about the estates of his father the 4th Earl Fortescue. From Page 4:

This Tattersall Estate came into the possession of my family about 1690, through the marriage of the Hugh Fortescue of the day with the heiress of the Earl of Lincoln, when it became her property (the male line of the Clinton family having died out), and has remained in our family until its recent sale."

These family connections led to a another branch of the Fortescue Family inheriting Boconnoc from the Pitts.
