Beech Tree Twig

SHOELACE TASSEL - Cornwall Golf & Country Club, Nutfield Tract Indian Reservation, Lot 11 / Concession 1

I wondered if these trees might have been planted as the original boundary line between Lots 10 & 11 on the Colquhoun farmland, but my mum said they probably aren’t 200 years old.  I don’t really know anything about tree identification.  Are these even beech trees?

I know Robert married Elizabeth McNairn, the first White baby born in Glengarry County.  I wonder how they met.
