Mrs Staham - do you mean he married a widow?
What sources do you have for them already?Middle names are exceedingly rare in this period (sometimes alias names are mistaken for middle names). All the sources for Richard (from his marriage and children) show his name only Richard Statham, and I don't see any sources that give his father's name.https://www.familysearch.org/en/tree/person/details/K6WQ-7RQ
