Tenorman on Family Tree Circles

I have traced my FULTON line back to Dunning in Perthshire, Scotland around the 1800s, and would welcome information from anyone also researching this line.
The earliest relatives are Robert Fulton (b. 1767) and his wife Louisa (or possibly Elizabeth) Henderson (b. 1775).
Another family I am currently interested in, is the CROFTS family from Margate, Kent, England.
Also Charles NICOLL (b, Dundee, Scotland in1817) and his wife Ann BRUNTON b,1815).
ALso the HORN family from the 'Braes 'o Yettes' farm, Kirkintilloch, Scotland, in the late 1770s and early 1800s.
Also William BRYDON (b.Edinburgh 1817) and his wife Joan Shaw PIPER (b.1819).
Also Donald McCALLUM (b. 1793 Argylshire, Scotland) and his wife Mary McRAE (b.1802).
Also Robert Dick McISAAC (b. 1830 Glasgow,Scotland), and his wife Ellen BRYDON (b. 1837 Edinburgh, Scotland).

All these families emigrated to New Zealand in and around the 1840s.
