Lijsbeth van Mieren

Yvette Hoitink has written a blog on 16 August 2019 containing all the evidence that proves that Jan van Wijfliet was a son of Jan Bac Berthouts van Tilburg and Lady Lijsbeth van Mieren, the illegitimate daughter of Jan van Wijfliet, lord of Blaasveld, and Lijsbeth van Mieren. She builds on the hypothesis that was put forward in 2002 by Hans Vogels in the Yahoo group soc_nederlandse_adel and presents new evidence which gives the exact name:

"Multiple records identify the father of Jan van Wijfliet as Jan Back Berthouts van Tilburg. No records directly identify his mother, but two records name his father’s wife. A 1349 rent register identifies a Lady Lijsbeth van Mieren, daughter of Lord Jan Wijfvliet and Lijsbeth van Mieren. The next line says “Jan Bac’s wife,” without making explicit whether that refers to the daughter or the mother. A 1391 annuity names Jan Back’s wife as Lady Lijsbeth.

A combination of evidence shows that Jan Bac was married to the daughter Lijsbeth van Mieren, not the mother:
- The 1391 annuity called Jan Back’s wife Lady Lijsbeth, the same title as used for the daughter in the 1349 rent register. The rent register did not use a title for the mother.
- Jan Back and Lady Lijsbeth named their son Jan van Wijfliet, apparently after his maternal grandfather, in accordance with tradition. Naming a child after a former lover would be highly unusual.
- Jan Back received a rent formerly held by Jan van Wijfliet. That type of transfer is more common from father to son-in-law than from nobleman to husband of his former mistress.
- An unreliable heraldic manuscript identifies the wife of Jan Back as N. Wijfliet, consistent with her being Jan van Wijfliet’s daughter.
- Jan Back was the son of Berthout Back, the steward of the Duke of Brabant. He would be of the right social status and traveled in the right circles to marry an illegitimate daughter of a lord who was himself the illegitimate son of the Duke of Brabant.

The combination of this evidence proves that Jan van Wijfliet was the son of Lady Lijsbeth van Mieren, the illegitimate daughter of Jan van Wijfliet, lord of Blaasveld, and Lijsbeth van Mieren"

Yvette Hoitink heeft op 16 augustus 2019 een blog geschreven waarin zij het bewijs levert dat Jan van Wijfliet een zoon was van Jan Bac en vrouwe Lijsbeth van Mieren, de onwettige dochter van Jan van Wijfliet, heer van Blaasveld, en Lijsbeth van Mieren. Daarbij bouwt ze verder op de hypothese die in 2002 door Hans Vogels was gedaan in de Yahoo group soc_nederlandse_adel en komt ze met aanvullende bewijzen waaruit de exacte voornaam blijkt:
