In a 2017 SGM thread concerning Philippa Bonville, Douglas Richardson makes the following statement:
“In contrast, we have the Grenville pedigree in Pole, Collections towards a Description of Devon (1791): 387–388, which reads:
“Willam Grenvill his brother maried Thomazin, & unto his 2 wief Phelip, daughter of Willam Lord Bonvill, & had issue Sr Thomas ...”). END OF QUOTE.
While I certainly respect Pole, he is not infallible. He makes Philippe the daughter of Lord Bonville. I should note that Pole was writing in a later period than the published visitation. In this case, I would give the visitation greater weight than Pole.”
This statement by Douglas Richardson is completely false concerning when Sir William Pole (b.1561-d.1635) was writing his Collections Towards a Description of the County of Devon. There is evidence that exists which refutes Douglas Richardson’s statement regarding Sir William Pole. The truth is that Pole was not writing in a later period than when the 1620 Visitation of Cornwall-Grenville pedigree was published in the visitation.
In the articles of Prince, p. 636, Risdon, p. 29, Introduction to Sir William Pole's "Collections," & c. Lysons, part ii. p. 136; we can find a description of the timeframe as to when the works of Sir William Pole (born 1561 – died 1635) were compiled and written. According to Risdon, “It is observed by his editor, in the Introduction, that what is published is little more than a common-place book to a much more extensive design, which the author had in contemplation so early as the year 1604, as appears from a letter of his published in this Introduction, the original of which is in the British Museum, Bibl. Harl. No. 1195, fol. 37.”
From the British Museum archives, it is apparent that Sir William Pole was compiling his works as early as 1604 when he was 43 years of age and finished it in the 1610s, well before Sir Bernard Grenville gave his original pedigree manuscript to the visitation heralds in 1620. The Grenville pedigree manuscript found in Vivian, The Visitation of the County of Cornwall in the year 1620, (1874): p. 84 (Grenvile ped.) was given to the heralds by Sir Bernard Grenville in 1620.
So, it is abundantly clear that Douglas Richardson makes another false assumption concerning the origination date of Sir William Pole’s Grenville pedigree. Just like so many other Antiquaries (Rogers, Burke, & J.S. Roskell) have done, I would give Sir William Pole greater weight in determining Philippa’s parentage than a flawed 1620 Visitation of Cornwall-Grenvile pedigree with proven errors in multiple generations!
