Wilsons in Ballyronan area

[mag mcdaid canny]

I am wondering whether you have any information concerning Wilson's 1820s -1830s possibly from Derry but could have moved to Greencastle/Moville area? Our GGGgranny Katie Wilson stayed and married our GGGgrandad, whilst the rest of the family left for America possibly late 1830s. We understand her siblings were Tom, James, Peggy, Majorie and Mary. Katie is said to have a twin Pat, who died as a baby. We understand there was no contact once the  ship sailed. We haven't found this family on any emigration lists as yet. Any help would be most welcome.
Many thanks
Margaret
