Hi, my family name is Johnson, or Johnston, based in Dunleer Co. Louth. I know that my family history ,originate from the 1800's with 3 brothers who moved from Scotland to the louth area. The next time I'm visiting my uncles, I'll see if they are aware of any possible links in the area or not. It's quite interesting, as was earlier suggested, my family are both Johnson or Johnston - something to do with changing the surname so as not to receive each other's post!!
