Judith Parnuit's parents are not known, and they do not appear in any reliable/reputable sources. The only sources claiming she is the daughter of a Nicholas Parrissot (1558–1638) and Marguerite Parrissot (1556–1623; neither of which I could prove to exist) are all user-generated websites like FamilySearch Trees, MyHeritage, WikiTree, Family Echo, etc. and they do not cite any sources. Furthermore, it would not make sense if her father was Nicholas Parrissot as her birth surname is Parnuit.
The sources all mentioning Parnuit have no record of her having any parents (and further confirm her maiden name):
*"Die Nels in Frankryk: nuwe inligting", (in Afrikaans) volume 3 of Famnea, published in Sep 2007, the quarterly journal of the Genealogical Society of South Africa.
*"Proceedings of the Huguenot Society of Great Britain and Ireland", published in 2007 by the Huguenot Society of Great Britain and Ireland. page 17.
*"Die Eerste Kaap Stamboom", published in March 2008 by Johana Nels and M. J. Bothma
As well as the website e-family.co.za, which often cites baptism and marriage records, but it is may not be entirely reliable for all info.
