Pleased to provide information that I have, particularly 8 generations of this family from Battle of Hastings participant Humphrey de Bohun through his descendants in the 11th-13th centuries. This file is 10 sheets and needs to be sent as an e-mail attachment. I will need your e-mail address to send.
Also have available a research document regarding 13th century Bohun burials at Llanthony Secunda Priory in Gloucestershire.
Anyway, let me know about the e-mail address. You can send your reply directly to my address.
