Beatrix of Silesia-Glogau: who were her parents?

[Tony Hoskins]

Two entirely different sets of parents are prominently claimed for
Beatrix of Silesia-Glogau (c1292-1322), wife of (the later) Holy Roman
Emperor Ludwig IV.

1) Leo's Great Site shows Beatrix as daughter of Bolko I, Duke of
Glogau (1252/6-1301) by his wife Beatrix of Brandenburg.

2) Marek's useful site http://genealogy.euweb.cz/ shows her as a
daughter of Henryk I, Duke of Glogau, Sagan, and Great Poland
(1251/60-1310) by his wife Mechtild of Brusnwick-Luneburg.

Leo was kind enough to inform me that his source was ES III/1 12,
although noting that Dr. Dek in his book on the Counts of Holland agrees
with Marek. [A.W.E. Dek _Genealogie der graven van Holland_, Zaltbommel
: Europese Bibliotheek, 1969].

Beatrix is ancestral to a number of us through her descendant Catherine
of France, daughter of King Charles VI.

Any thoughts or information would be appreciated.

Many thanks.

Tony
