The senior line through James leads to an intriguing situation; in 1714 he married Sarah Lay of nearby Tey, the first of four generations of the Lay family who successively married into the Josselyn family.
They had a family of three sons, James, John (who died an infant) and Mark.

Next in line was their eldest son, James (G5), (bl717) who in 1747 married Sarah, daughter of Mark Lay, having twelve children of which at least five died in childhood.
James Josselyn (G4), b1748, married Margaret, daughter of John Lay of Lt Horkesley. They resided at Wakes Colne, Essex and had two sons, James and John, plus four daughters. Margaret died aged 30, two years after the birth of her youngest daughter.
There was a further Lay involvement when Elizabeth (G4) married Margaret's brother, John Lay in 1781; there does not appear to be any issue from that marriage.
Their eldest son James died without male issue and the senior line of this branch continued through the second son John (G3), b1780, who again married (1815) within the Lay family, his wife being Mary Anne, daughter of Mark and Elizabeth; they had a son John and daughters. His wife remarried twice after his death in 1820, at which time they were living at Boxted Hall. (Volume 1 covered the marriage of Mary Anne's sister, Elizabeth with Thomas Hallum.)
John was a student of Corpus Christie, Cambridge; he was Deputy Lieutenant for Suffolk and High Sheriff 1855. He was also Master of the Suffolk Hounds 1845-64 and 1867-70.

This line of the family had thus relocated to Suffolk and, with issue of five sons and two daughters, firmly established the family in that region, although only one son of this line, Willoughby, had further male issue to carry forward the Josselyn name.
John Josselyn and his wife Mary were buried at Rougham, Suffolk.
