Wilding/Llangullo & a lady believed in their service!

[MrsBear51]

Greetings,
My first time here and I'm after some help/advice, please?
I am researching a family tree on behalf of a family friend and I am looking for pointers on how to find any information on a lady called Elizabeth Owen(s), born about 1803 (assuming she was 21 when her son was born, she could have been much younger and location of birth unknown).
She had a son called John Owen in about 1824, Bromfield, Herefordshire.
The family of John Owen(s) believe that his mother was in service as a housekeeper or similar in a place called Pennyclaud (no idea of the correct spelling), Llangullo with a family called Wilding and John was illegitimate as a result of a liaison (forced or consensual) between his mother and one of the Wilding men.
I am an experienced family tree researcher, but due to the years of birth and locations that are unfamiliar to me, I'm struggling to make any headway. I do not know if John had any siblings, so can't find him via that circuitous route.
I have a marriage cert from 1852 where he married a lady called Harriet Webb in Hatfield where he lists his father as being William Owens a farmer (the family think this is a fake name), with the bride coming from Hatfield and the groom coming from Richards Castle, Salop.
Due to the lack of 'official' documentation from anything prior to 1837, I am happy to admit defeat, but not before I've asked a few questions to those who might know.
Any thoughts would be most gratefully received.
Thank you.

This is I think the property you're looking for

There are definitely Wildings at that property, but towards the end of the 19th century

There is this. The name and birth year fit, but not the birthplace. Was he born in Herefordshire or Radnorshire? https://www.familysearch.org/ark:/61903/1:1:V552-8GL

Thanks all
@Talacharn I am aware of the 1871 census returns you have very kindly posted. It is on behalf of one of these children's relatives that I am doing the research. I have found that Richard varies his location of birth a bit when providing information for the census, but I am happy that they are the right family as there aren't too many Lechmeres around.
@Trish1120 - fantastic bit of detective work - I think it probably is a brother which gives me a little more to work with.
@Mabel Bagshawe - thanks so much for finding that - as far as I'm aware, most of Richards children more or less all became farming folk, so there stands a good chance that is where it all started.
Thank you!
