My mtNA is L4b2b and my ancestor was thought to be Maria Bellardy but now thought to be through Jannetje

Mother-Putative* Maaij Claesje van Angola b. c 1645; This putative relationship is offered on the following grounds: 1) Claasje baptised a daughter named Jannetie on 27 Oct 1675, and at the time there were no other company owned female slaves named Claasje (var.). 2) Jannetje van Wijk closely fits the profile, including age cohort, to be this child. 3) A direct matrilineal descendant of Jannetje van Wijk has tested positive for mtDNA haplogroup L4b2b - a rare group which current informatoin suggests is centered in northwest Africa around Mali. This strongly suggests that Jannetje's mother would have been one of the slaves generally identified as 'van Guinea' or 'van Angola.' Many of these slaves were embarked at Benin for the Cape and came from as far afield as Sudan. This further suggests that this mother-daughter relationship is indeed correct.
