Can someone with Pre 1500 certification confirm the ancestors of Elizabeth D'Oyly D'Oyly-47?

Question

The ancestors of Elizabeth D'Oyly [D'Oyly-47] are believed to go back to the Norman Conquest to a Robert D'Oilly who came into England with William the Conqueror and built Oxford Castle. I need someone with pre 1500 certification to research and confirm her ancestry. Thank you.

Answer 1

Matthew it would help if you could find the sources and add them here and assist the small group of pre-1500 accredited volunteers. They will be very appreciative of your work.

Please follow the D'Oyly line. It will take you back to the 11th century. I need someone with pre 1500 certification to confirm the history of the D'Oyly family. Thank you.
