They migrated to County Durham, England sometime between 1863 and 1866. I have most of the information on them from Durham census's after 1866.
Although I found their marriage in 1850 on emerald ancestors website, and got details from them, there is no further information regards the family on that website.
marriage details i have state:
Married in the Parish Church Maghera, according to the rites & ceremonies of the united church of england & ireland, by licence, by me James Spencer Knox, 5 jul 1850.
this is a transcription i recieved from emerald ancestors website, so not sure.
