Hi Lynn,
Yes, I was trawling for something else when I saw your question.
The following needs double-checking but here goes;
Thomas's father is John c 1705 Rostherne and his mother is Ellen Burgess 1706-1776 Rostherne, they married 25/12/1734 so I guess there are older siblings.
John's father is another John 1675 High Legh and his mother is Jane ? 1678 - c 1709 Rostherne.
Ellen's father is Edmund Burgess 7/10/1679 Rostherne who married Mary Jackson c1693 Dunham Bowden. They married in 1707 so Ellen may have been illegitimate.
Edmund's father was also Edmund c 1652 Rostherne and his mother was Mary Armston c 1656 Rostherne, they married, also on Christmas day 1678.
Hope This helps,
Mike
