MCCRACKEN m BORLAND 1830? Ayr Scotland

I'm looking for any information I can find on Alexander McCracken and Elizabeth Borland married around 1830s.I have the OPR and marriage certificate of their son Alexander born 29 Oct 1833 Riccarton Ayr,(whom married Jane Campbell YOUNG 21 Sept 1860),which I managed to extract from the Scots Origins website but have come to a standstill now. I'd appreciate any help regarding sites etc.

Thanks Robyn McCracken
