In 1861 both Mary and Sarah are unmarried; William is listed as Mary's grandson (Sarah's son?) yet in 1881 he is Sarah's brother. Sarah is a dressmaker on both.

Many thanks to Sam from Stoke and Potty for their help obviously Mary was unmarried when she had Sarah and it will be very difficult to trace her parents as she was born c1815 when records were sparse.Kindest regards to you both.Dave.
