Anne Heydon and Roger le Strange

If anyone can help me with the parents of Anne Heydon and Roger le
Strange, as well as their children, I would appreciate it very much.

What I am actually trying to straighten out is the ancestry of Thomas
Gray, the Ancient Planter. Most seem to agree that his parents were
Catherine le Strange and Edward Gray - it is Catherine's history that
has me bogged down.

Thank you!
