Your right the original concord covered a much larger area than the South of the River Concord as we have today.
Kissing Point is on the North shore in Ryde area and was an original part of Concord.
I cant get any listing for the Farm, unusual

But it must have been there and I think on the north side as it had the orchard.
Will keep looking, spent a bit time in that area a couple years ago.
