In relation to John's parents being Richard and Mary, thank you sooo much for that line as I had John's parents as Thomas and Ann due to a 1841 census with this John being 3 years younger and also born in Oundle, Northamptonshire, Eng.
I only got triggered to Richard and Mary after John's wife, Sarah died he was listed in 1871 as a widow with his daughters Catherine bn 1852 Oundle and Eliza bn 1856 Thorney, Cambridgeshire...
I didn't have catherine down from previous census's because in 1861 she was with Grandparents Richard and Mary and later living with a Spinster Aunt Sarah as Catherine also remains a Spinster and Aunt Sarah's mother is also living there...
Wilfred and Catherine are obviously maybe twins...yet to confirm but they are both born in 1852 Oundle.
Again Can't thank you enough...
