Hi again WY

I've been working through the records and census info to try to decide whether or not your Richard is the son of Richard and Mary or William and Jane.
I'm about 90% sure that he's the son of Richard and Mary (his age is consistent with the 1826 bpt throughout the censuses) but there's that doubt still

Is it possible for you to get Richard and Martha's marriage cert to make certain?
In the mean time, I have these baptisms to Richard Roberts and Mary, listed as living either Halton or Green Lane:
Maria Roberts bpt 20 August 1820
Harriett Roberts bpt 25 April 1824
Richard Roberts bpt 20 Aug 1826
Thomas Roberts bpt 3 Oct 1830
On 1851 in Chirk:
Woodside Cottages (* only a few households away from Richard, jnr, and Martha)
HO107/1993/ 806/13
Roberts Richard,widr, 68, coal miner, b. Salop, Oswestry
Harriett, d, 27
Thomas, s, 20
Robert, s, 5
All b. Chirk except Richard
Possible birth for Richard (IGI)
Oswestry 21 March 1785 (bpt. 23) Richard s/o John Roberts and Jane
I'm still trying to fathom out whether Mary was a Cash by marriage ar by birth. You may recall that she was down as a widow on the marriage entry.
