Unfortunately I know little about John Parving born 1811.I know that his second wife was Elizabeth Palliser and they married in 1851 at Sand Hutton.The marriage cert. says that his father's name was John.The Census returns for 1851, 61 and 1881 said he was born at Sand Hutton. John had a son Thomas by his first marriage, and three children by his second,William, Esther and Hannah. Which of these are you descended from?Have copy of marriage cert, also census entries if you are interested.Would also be interested in knowing of the descendants of John. I have a fair amount of information on Yorkshire Parvins, which I would be glad to share with you.
