Hi Julieann1.
A bit late, but just found that some of my cousin's family gradually worked back to Ayr.
John McTaggart b.1789 Kirkoswald & his wife Janet Goudie b.1795 Kirkmichael, last seen 51 Mill St. Ayr.
Alexander Dunlop b. 1825 Ayr & wife Janet McTaggart b. 1825 Ayr, last seen 51 Harbour St.Ayr.
Nothing after 1851, may have moved by 1861.
