I see the thread is 16 years ago.
I believe John and Sarah were also parents named somewhere but he was born in 1811 and came to America in 1832 with a brother, who died from disease on the boat.
Sounds like your John might have been a Jr, since the names in the church yard at Worboys when I visited in 1992, were all the same names of our clan in Illinois,
I've a picture of my great grandfather Mortimer in 1922 at a picnic with family, if you are interested.
