There seems to be a large number of duplicates with this family. I've always considered for older records, the year of birth more likely to be accurate than 2nd hand information on a death notice. I think the birth dates on the MOOC for 8 of the 9 children is incorrect. it appears that the Francois Gerhardus (the youngest child) possibly died young. but the rest is in the same order as their birth/baptism records and unlikely that they had a few children with the same names born on different dates. It also appears that information on the 2 Neethling sisters were combined and contributed to the confusion.
Basically SAG is largely correct - only two errors for the Gerrit son b1 and c1-c8 i.e. 2nd marriage to Gebrecht Vosloo (this is not correct she was married to Barend Frans' son) and the 9th child was not recorded in SAG.
I am helping someone with their Lotriet ancestors and we want to update the profile but would like to get some input on this matter first.
Thanks
