Charlemagne Line??

Hello all, trying to connect to Charlemagne...Can anyone tell me if this
line is accurate:

Charlemagne - Hildegardis von Vinzgau
Louis I the Pious - Judith von Bavaria
Winidilda de Ampurias - Wilfredo I of Barcelona
Suniario I de Brel - Richildis de Rouergue
Borrell II of Barcelona - Leodegarda de Toulouse
Ramon Borrell - Ermesindis de Carcassonne
Ramon I Berenger - Gisela de Lluca
Sibylle de Barcelona - Henry of Burgundy
Henri de Bourgogne - Teresa de Castilla
Afonso I of Portugal - Matilda of Savoy

Todd A. Farmerie...

Again, no evidence for her name, and her origin is speculative.

Todd A. Farmerie...

The origin of these two wives is highly speculative, and alternatives to
Toulouse have been suggested for each.

Todd A. Farmerie...

She was not "de Longwy". This was based on a misinterpretation of two
pieces of data, plus some added speculation by Szabolcs de Vajay. He
has since retracted this identification without qualification, and there
is reason to believe that the supposed father Albert of Longwy died
without marrying, nor is there any evidence that Stephanie derived from
this region. Her parentage is one of the great genealogical puzzles of
the period.

Sancho I of Portugal - Maria Pais da Ribeira
Teresa Sanches - Afonso Telles de Menezes
Joao Afonso Telles de Menezes - Elvira Gonzalez Giron
Goncalo Anes Raposo - Urraca Fernandes de Lima
Afonso Martins Telles de Menezes - Berengaria Lourenco de Valadares
Martim Afonso Telles de Menezes - unknown
Joana Telles de Menezes - Joao Afonso de Pimentel
Rodrigo Afonso de Pimentel - Leonor Enriquez de Mendoza
Alfonso de Pimentel - Maria de Quinones y Toledo

Any feedback would be appreciated.
