Sorry to be so slow responding. I kinda let my genealogy go dormant for awhile.Need to get back into the swing of things.I am pretty positive my McGillick's are from the Kells area of County Meath.John was clearly Patricks' brother and his tombstone says Kells, Meath.Parish records show a family in the area with a John & Patrick - correct ages so I think we found them. Just need to know more.
But I am sure all are connected somewhere - not a common name.Lough & Meath are definately neighbors too!
There was a Peter McGillick in they Yankton area of SD by about 1870 - I can't remember the exact year but it was well before SD became very populated & that's pretty early for here (1889 was statehood).He appears to be unrelated to my line but I noticed you had a Peter in yours.I don't remember other names from his family but if you have any that disappeared I can dig through the census and see if I can find them.It's been a few years since I found them but I'm sure I kept the info ...just in case.
You mentioned dropping the "Mc" - there are some Gillick's in Ipswich SD - which is where Patrick & Catherine are buried.I always wondered if there could be a connection but we haven't found one .. yet.
I will keep your McGillick's in mind & let you know if I run into anything.
Made it to Ireland in August of last year but unfortunately had a lot of stuff to see.On the Kells visit went to a few cemeterys - they have very few stones that are old and every place we went the church was closed that day - or the person who had the records was gone etc. Have to go again!
