Many thanks for sending me details about your Gilmour family Barbara. From your info it is clear I may be following the wrong line.
My line is from James Watt Gilmore/Gilmour who married Julia Martin 15 Jun 1863 at Kirk Maughold.

I had provisionally placed my James as the eldest son of James Gilmour and Ann Watterson (making an assumption that the Watt came from Watterson) But you have James maried to Louisa Peel.

I will send for the marriage cert. of James and Julia as I should have done in the first place.
