Many people who chose this name did have ancestors from the area of the little stream called Boorne,
and the town 'Oldeboorn'.
" stra " does mean: from that area, or from that place.
Boo(r)n-stra is then the name that does come up
The problem with our family is that we cannot find connections
from the area of the Boorne, probably there must be other roots as well for this name.
But all names with the end of " stra " are sure Frisian [Friesland]
