A tree on ancestry has Simon marrying in Cambridgeshire 11 February 1812 to Sarah Hayden,
so I would check Meldreth Cambs parish records, Susan as a possible first child may have been baptized in her mothers parish. She would have had to have been born less than 9 months from the marriage date otherwise Isaac could not be baptized May of 1813.
There is a strong case for a connection, when she married George Prime 12 June 1832 the witnesses were Isaac Patten and Elizabeth Patten
