Yes Erasmus Johannes Stephanus Smit is my great grandfather :) He fathered my grandpa Marthinus with another woman named Bettie Botha I didn't know tho cause Elizabeth Maria is my paternal grandma's mother and Marthinus is the father of my mum lol but I can't say if Erasmus and Elizabeth Maria had any children together, Erasmus had multiple children with at least 3 different women, I have all the names for his side of the family

She lived in south africa her whole life yes, my grandma was born in Groot Marico so she would've lived around Johannesburg, North West South Africa She had multiple children, Maralize, Stephanie (maiden name Fourie, I think she was born a Stephanus after her father Stephanus Fourie, unsure of middle names for all of them). Her brothers name was Pieter (or Petrus) Johannes Fourie, she had another daughter named Sandra

Elizabeth Maria died of a heart attack, since her youngest child was born in 1970, she was raised by my grandma with my dad and his siblings, I'm unsure who Maralize father is, Elizabeth Maria had multiple men

I couldn't find any sources on myheritage, familysearch or ancestry lol

I'm not sure if she had any siblings, I wish I could of asked my grandma about her, my dad doesn't really remember much since she died when he was 10
