Hi Geno500
I see you posted this quite a while ago, but do get in touch with me if you have any further information on the Crosses. I believe Roderick Cross might have been a brother of one of my ancestors, Alexander Cross, who was a witness at the marriage of Roderick's daughter Isabella. Alexander was born in Dingwall, Ross-shire in 1797 (near Kiltearn where Roderick lived), and was a son of William and Anne Cross.
Cheers
Arie
