Question

I cant find any records for Marchbank/Marjoriebanks or Johnstone before the middle 1700.

Answer 1

Marjorie Johnstone born 27 June 1765 Edinburgh Parish,  Edinburgh, Midlothian, Scotland

Father is David Johnstone.

Answer 2

Your question isn't very specific as to names and locations?  There are lots of Marchbanks/Margbanks and Johnstones  with christenings etc. in Scotland between 1700 -1725

Comments

So the last person I have on my record is James Marchbank 1787-1875 (my 3 greatgrandfather) born in Dumfries, Scotland, married to Mary Walker   When I search for James Marchbank there are no profiles linked to this James and I don't know how to find any more info than I have to validate any source for who his father and mother are.
