Sharon, re your question about Maaij Claesje being from Angola:
L4b2b - is according to TFFYP "a rare group which current information suggests is centered in northwest Africa around Mali".
Doesn't sound like it's likely to have been found in Angola -or surrounding West central African populations where the Amersfoort slaves are likely to have originated.
It's possible of course that once in S.A. the exact origin of a particular slave may have been forgotten or been of so little significance the "van Angola/Guinea" toponym was misused. But I have yet to see any instance of Angola/Guinea being used interchangeably.
A close scrutiny of the FFYP page reveals that the toponym "van Angola" was never applied to "Claesje" directly in the record.
It appears to result from an ASSUMPTION that "Marselij van Angola" who appears in the record from 1652-60 under that name ....was the same individual named "Pollecij" from 1666-1669......and then named only as "Claesje" from 1671-1689. :0 !!!
I think this all needs to be re-examined. What was the reason for this assumption that Marselij/Pollecij/Claesje is the same person?
