I can add an element of confirmation and probably some more mud!
Faith Ludlam married John Wright in Tetney on 15/5/1759. She was baptised in Tetney on 24/2/1736-7, the daughter of Thomas Ludlam and Faith (born Wardle). However, this is likely the third, latest marriage between Ludlams and Wrights in this area.
Prior to this Elizabeth Ludlam (bp 14/7/1683 Hemsworh, Yorks) seems to have married John Wright - marriage record yet to be found - and Mary Ludlam (bp 28/9/1693 Tetney) married Edward Wright at Yarborough on 6/4/1717. Both women were daughters of Stephen Ludlam, vicar of Tetney, who died in 1722. Faith's father Thomas was a son of the said Stephen.
Ludlam wills are of value for a few more items.
The will of Stephen (1722) names Elizabeth and Mary as wives of John and Edward respectively. The will of William Ludlam of Tetney (1765) gives the following names:
Brother Thomas
Children of Thomas: Ann, Thomas, Stephen and Jane
Nephew William Ludlam
Jane Faulding, widow
Ann and Susannah Ludlam
Nephews William and Stephen Wright
Mary, daughter of said nephew Stephen Wright and his two sons, Stephen and William
Nephew John Ludlam executor
William Ludlam was another son of Stephen.
Hope some of this helps...
