My great grandmother, Mary Mansfield, 1830 -1910, was brought up on Pinfold farm. On marrying Richard Mayou she moved next door to Field Gate Farm then to the Mayou family farm at Sheldon. I see that 1841 census has Thomas Mansfield,his wife, 4 sibs and 2 servants. 1837 tithe shows that Thomas owned 64 acres in Yardley. I have a needlework panel by Mary Mansfield dated 1845 and with anote on frame "Yardley Ladies College".
I would be interested to know more of Mansfield family and Pinfold farm (and indeed the Mayou family of Sheldon, Coleshill etc.)
