Claassen / Du Plessis around early 1800's
Can anyone help with information on Aletta Elizabeth Claassen (Claasen) and husband Petrus Johannes Du Plessis. They had at least one child Johanna Herkolina Du Plessis who died in Parys 25 Sep 1961 who was married to Strydom Johannes Strydom. I have both versions of the Claassen name listed in family records and am not sure which is correct. Information about any of these people will be most appreciated.
