Hi Jemstone:
As soon as I saw your posting, I thought it must be our Holm clan and it could still be.
I have traced the Holms back to the late 16th century, so I will do a bit more delving,
I do have a William Holm marrying a Margaret Williamson in 1802 in Cromarty, R&C.
Will get back to you.
Kind regards
