Here's a lot of information
Stamvader van die Esterhuys-familie (Hersiene Uitgawe)
He seemed to have had a lot of knowledge about the Fries way of farming, so maybe Friesland is also an option and according this the last name was given to him after arrival by the company clerks, so this wasn't his original LNAB, so his original last name at birth could be any, maybe a last name but a patronymic is a possibility as well I assume ?
Looking for a place ... since it is mentioned he could not write and assuming his pronouncement of the place in Fries was somehow translated and written down by the clerks as Esterhuysen , maybe the place Idskenhuizen or Easterein (Oosterend)
An ''Esthuys is a stone building , often with a cone-shaped roof and a plurality of chimneys, in which the hop was and is still sometimes dried, often in the immediate vicinity of hop fields '' (looked for it in the archives and is mentioned in a lot of Dutch Notarial deeds where houses ,a shed and sometimes an ''Esthuis'' as well are sold or bought)
Looked at his wife as well if maybe this could give a clue if maybe they married in Groningen or Friesland already), her father was Andries Beyers ''he arrived from Saxen as a soldier at the Cape in February 1672 on the ship Wapen van der Gouw.'' No further clues..
But...assumed they named the children after the grandfathers , it would mean his father probably was named Jan ( or Joannis /Johannes), the first child named Jan, died young and after his death another child was born and named Jan Andries (after both grandfathers ?)
In the Fries archive only three children :
* 11 November 1670, Leeuwarden Cristoffel son of Jan Crisstoffels
* 27 April, 1670, Leeuwarden Christoffel son of Joannis Chrisstoffels
* 4 July, 1669 , leeuwarden, Christoffel son of again Joannis Crisstoffels and might be the same as above father ? (this could mean this child Christoffel died young which leaves only these two options., and both born in 1670....
Assumed the child was named after great grandfather :
* 4 March , 1660 Harlingen , Christoffel son of Christoffel Jans and Berber Freercks
* 18 December, 1659 Harlingen , Christoffel son of Christoffel Jans and Entje Teekes
Same search in Groningen gives:
* No children named Christoffel that could fit his date of Birth . All Jo(h)ans or Jan Christoffels Groningen and all Christoffel J(o)(h)ans
The names Wilhelm and Jurjen could come from the Beyers family , I know it's mentioned above he arrived as a soldier from Saxen, but there are some Beyers in the Fries Archive as well , named Hans Jurien Beyer here's a different one also named Hans Jurien Beyer and a Wilhelm Jansen Beyer (heer)
In Leeuwarden at that time was a Beyer street and or area named the Beyer, people without last names are mentioned in records as from the Beyer or living in the Beyerstreet
