my great-grandfather was given a detailed family tree of the yelvertons by an old friend who researched it for years. containing details of each person's life where he could find it. it goes right back to William De Yelverton at the time of william the conqueror (with big gaps). and charts the yelverton's move to ireland and back. i will get a copy from my dad and post the info somehow as it was fascinating for me to read through as a child. infact, it will be lovely to go over it again. feel free to ask me questions about names that may appear on it. it may take me a little while to get a copy and i haven't read it for years so i can't reply instantly. my memory of it is sparse!
