we see Sidney Mostyn married
Sir Richard Grosvenor of Easton, 2nd Bart and by him had
Roger Grosvenor abt 1628
This couple had another daughter
Sydney Grosvenor who married Thomas Hesketh of Rufford and by him had at
least two children
1) Robert Hesketh of Rufford married Elizabeth Spencer thereby giving birth
to the future Elizabeth Hesketh, Countess of Derby b 1694
2) Thomas Hesketh of Rufford married Anne Graham dau of Sir Richard Graham of
Norton Conyers.
Now thanks to
"The Royal Families of England, Scotland, and Wales, With Their Descendants,
Sovereigns and Subjects". Volumes I-II, Burke, John and John Bernard Burke,
London: E. Churton, 1848-51
I can give these boys a royal ascent which Leo is not showing.
Per this source, Sydney is a daughter to Sir Richard Grosvenor of Eaton.
Chronologically this is likely to be the 2nd Bart, althought it could be his
father I suppose, but that does not bear on the remainder of this lineage.
The royal ascent is through Thomas Hesketh of Rufford. The subhead is
"Hesketh, John Lethridge" and the line goes as follows
Thomas Hesketh of Rufford m Sidney dau of Sir Richard Grosvenor of Eaton
son of
Robert Hesketh of Rufford m Lucy dau of Alexander Rigby of Middleton
son of
Robert Hesketh of Rufford d 1653 m Margaret dau of Alexander Standish
son of
Robert Hesketh of Rufford m Mary dau and heir of Sir George Stanley
dau of
Sir George Stanley of Cross Hall Marshall of Ireland
son of
Sir James Stanley of Cross Hall, Marshall of Ireland m Anne widow of Edmund
Talbot of Bashall and sister of Sir Percival Hart
son of
George, Lord Strange KG d 1497 and Joan dau and heir of John, Lord Strange of
Knockyn
at this point I believe the lines continues in Leo's database.
With this fine I've merged not less than three distinct lines of research
