I am looking for record of marriage for

James Elliot & Margaret Patterson.
Father of Margaret is John Patterson.

Their children were;

James Elliot baptised Kirk Santon 05/04/1801

Thomas Elliot ??

Margaret Elliot christened Santon 08/04/1803

Sidney Smith Elliot ( who was a female) Christened 19/05/1805 Santon I O M

There may have been other children born to these parents but as yet have found none.
Any help appreciated.
