Cupido

I am seeking information about the Paarl Cupido’s, specifically Isaac and Lizzy (Elizabeth) Cupido. I am looking for information about their ancestry. Their children were:
William, Phillip, Myra, Abraham (later changed his name to Arderne) and Elise.
I am attempting to construct my family tree. If you know any information that may be useful I will really appreciate that.
Thanks
Alherne Cupido
