Forgot to mention that the wife he lived with in the USA and maybe even already in SA (1901-1910) was named Wilhelmina Gunther. Most likely of Dutch origin.
Other great news for SA Pay family researchers is that two of his SA children (Violet Florence and Arthur Alfred Arnold), from his 1st wife (Elisabeth Augusta Wollenschlager,) married and had children in SA.
Pls check out much more recently scanned and published SA files on eg. FamilySearch.
