I have Astons in my tree and have parents for a 1721 Edward as Edward & Sarah.
Edward bapt 1681 son of Philip & Maria. My line is via Richard Aston & Susan Evans

Your 2nd point was James 1825 son of Edward, he was son of Edward Aston & Susan Jones, who married Jane Smith daughter of James Smith & Sarah (have been unable to find a marriage not listed in the GFHS marriage index, so could be Monmouth. James is son of Henry Smith & Jane Evans.

I hope this helps,

Gill Webb
