Stuart,
Glad to help further if possible. You wrote: <<Do you know what the connection is, if any, between the Mulahorn Wilsons and my John Wilson of Glendavagh? From the looks of things my great great grandmother was one of three Wilson girls, the other two being Maria and Jane. It's confusing though because there are lot of Wilsons in the Minterburn church records. >>
Does this mean that you found two other Wilson girls -- Maria and Jane -- to be daughters of a John Wilson of Glendavagh, possibly from their marriage records? Or did you identify them as sisters of Margaret Wilson (who married John McKenna in 1852) through other sources, documents or family stories? And are you a resident of Ireland that you can check back over Minterburn church records? Or, if living elsewhere, did you copy all the pertinent Wilson entries when you were in Ireland? If so, I'll be glad to help you sort out the families by analyzing the Wilsons in my research notes with the Minterburn families' births/baptisms and marriages. There were Wilsons of the Dyan (have you seen their extensive family chart?) and there were related Wilsons at Glenkeen.
Glendavagh is a very ancient townland, and I've found deeds and leases back to the 1760s-1770s there on my Haddens and related families. The oldest mention of it in the Registry of Deeds seems to be about 1708. Then we come forward about 50 years and I found that on January 21st, 1767, John Marshall of Mullaghmassagh granted to Archibald HADDEN part of Glendavagh which "said John Marshall held by a lease renewable forever" from Henry Marshall, to hold subject to redemption on payment of £100. On October 22nd, 1783, Joseph Marshall of Mullaghmassagh devised to John WILSON part of Glendavagh for 31 years at £14 sterling.
So my Haddens and possibly your Wilsons were neighbors at Glendavagh.
Glendavagh can be found under various phonetic spellings and interpretations in old records, including these:
Clondaw=ghy - 1609
Clonedaughie (?)
Clandaghy (?) - abt 1655
Clundavagh (?) - 1664
Clondaugh - 1666
Glendavogh, Glendavagh, Glendavogh, Clondavagh - abt 1691 in Aghaloo parish vestry books.
I'm very interested in the townland and its families. Would you like to write me personally and we'll go over further records?
Regards,
Annie
