The image of his baptism in the register for Great Witchingham, Norfolk has this record, transcribed by me:

“1734
. . . .
“John, the son of John Morris esq And Anna his Wife, who was the Eldest daughter of Tho Carthew esqr of Benacre in ye County of Suffolk, was Baptised April ye 15th 1734 having been born ye 12th.”

In his will of 26 June 1770 with docicils of 22 Aug 1770 and of 11th March 1775 and of 28th Nov 1775 and 2nd Dec 1776, he appointed Thomas Brograve and Thomas Quarles executors.

In his will he mentioned:

In “Church Heraldry of Norfolk” by Rev Edmund Farrer, pub Goose & Co in 1887, p. 388:

“This Marriage was solemnized between Us [signed] John Norris   Charlotte Townshend
“In the presence of  Thos. Townshend   Dor Cowper.”

Her father had died six or so years earlier, so I wonder if Thos Townsend was a brother or an uncle who gave her away.  Dor. Cowper was indeed her aunt, having married a Rev Spencer Cowper, Dean of Durham.
