Martin's Magnum Opus to verify from original contemporary sources all that he could of our forebears and of the old family records.
First published within the family in c.1984.
Deposited with the London Society of Genealogists.
In 1999, still being revised.
9. Reginald Cecil Lybbe Powys-Lybbe, Powys-Lybbe genealogy.
These are the various documents he left behing summarising his researches. They included:
(1) His master tree of all families married by our forebears.
(2) His formal pedigree of the Powyses, in the style of Burke.
(3) His two pages of trees of various descents from medieval royalty, including the Trotters back to the Scottish Stewarts.
(4) His trees of the recent Trotter marriages.

Remarkably most of this has proved to be confirmed by publicly available documents and some of it is a remarkable set of findings. One or two errors have appeared, mainly where he got the wrong wife as the ancestor. Perhaps only 20% of this remains to be checked, principally the families married into by the Trotters in the 18th and 19th centuries.

However his besetting and frustrating fault is his almost invariable omission of sources and similarly of dates.

I suspect he relied heavily on Burke's Extinct Peerage, judging by the heavily thumbed copy in APL's possession in 1999. But there is also evidence that went to various libraries and paid handsomely for primary documentary evidence of some 16th and 17th century families.

Nevertheless most of my work has been to extend and verify his enormous efforts. He really was a serious genealogist (like Martin but who follows the stricter regime of the last quarter of the 20th century) and I have considerable admiration for what he found out.
