Hello
I presume you have Richard's baptism in Frodesley 18.8.1743 illegitimate son of Susan Hickman which does suggest that he was born there.
I think Richard Everall of Leebotswood married Sarah Botfield there 29.5.1732.
He remarried Catherine Thomas of Frodsley 28 May 1739 at Leebotswood.
His Will of 1779 does not mention any Hickmans only sons Richard and Peter and daughter Sarah Wrigley and their children.
I'm assuming he was born in Leebotswood and christened there 15.3.1690 s of William and Margaret.
Siblings Rebecka 1681, William 1682,Margaret 1684,Margaret 1686,Samuel 1687, Richard 1690,Thomas 1695,Jane 1697.
Then as you know Susanna Hickman d of Alexander and Martha was born 1721 over in Frodesley.
Father Alexander born 1687 s of Richard and Mary.
They married by licence 17 Mar 1676 Richard Hickman and Mary Sankie.
Richard's Will of 1735 gives no clues.
So no obvious connections there ,but what could Martha's maiden name be?
Rowland Harley born 25 Mar 1707 Ditton Priors s of Rowland and Elizabeth
He married Joan Sherwood 5.9.1733 at Quatford.
It looks like mom was and Elizabeth Griffiths.(marriage Ludlow 2.7.1700)
Rowland senior may be son of Richard Harley and Margery Hawes of Morville.
That's where I get stuck I can't see any other records for the Langfords except what you have.
The only Langfords there were born in the 1680's.
It's a matter of trying to match them up with the other families and find more on each.
Good luck with your researches.
