Hi
I have a brochure/booklet from Adlington Hall which is the home of the Leghs of Adlington, which shows the male line and their wife's (but unfortunately not all of the individual children)
You could perhaps contact the Hall 01625 829206 to see if they have any knowledge of Margaret Legh. I don't think it is open to visitors any longer as I believe the family have recently left and it was being sold. However I think a caretaker may still be in place there.
There are numerous Thomas Legh's dates as follows -
1452-1519 - Wife Catherine (daughter of Sir John Savage)
1527-1548 - Wife Maria (daughter of Richard Grosvenor)
1547- 1601 - Wife Sibilia (daughter of Sir Urian Brereton)
1593-1644 - Wife Ann (daughter and co-heiress of John Gobarte)
1614- 1687 - Wife Mary (daughter of Thomas Bolles)
1644- 1691 - Wife Joanna (daughter and heiress of Sir John Maynard)
The brochure/booklet lists the tree starting with Robert De Legh (1308-1370) whose wife was Sybil daughter of Henry De Honford. He had a second wife Matilda who was the daughter and heiress of Sir Adam Norley.
However the history of the owners of the Hall goes back to Saxon times when Earl Edwin built a Hunting Lodge there. It became the ancestral home of the ancient and noble family of Legh, when the daughter of Hugh De Corona, Lucy had one son Thomas, who died childless, and two daughters Ellen and Isabel. Ellen married John De Legh of Booth and during the reign of Edward II, Thomas granted Adlington Hall to John and Ellen for life.
There are 14 generation between 1308 and 1644 - 6 x Robert's; 6 Thomas's; 1x George; 1x Uriah, and a further 13 generations post 1644.
Hopefully this gives some insight into the family history.
