Hi Judy
Your greataunt's name is familiar and I may have corresponded with her in the distant past. I attended the 1997 Waldron Clan Gathering, but not the 2000 one, so I probably never met her. I had a quick skim through the Waldron Clan Journals and membership directories, but didn't spot any mention of her, not even in the extensive report on the 2000 gathering.
Some general advice on your quest:
* include Waldron as a tag in your G2G posts (you can go back and edit the tags for your previous posts)
* join the Waldron Clan Association Facebook group
* invite your mother to sign up on WikiTree
* upload your AncestryDNA data to FTDNA if you have not already done so, as you have done at GEDmatch
* join the Waldron project at FTDNA or, better still, persuade a male Waldron uncle, cousin, etc., to do so and club together with family members to purchase Big Y-700 analysis for him
While civil registration of births, marriages and deaths began in parts of the so-called United Kingdom of Great Britain and Ireland in 1837, unfortunately the kingdom was not united for genealogical purposes and civil registration was not extended to Ireland until 1 Jan 1864, so will be of no help in your search for an ancestor who left Ireland in 1862. Church records can sometimes help before 1864, but unfortunately for many parishes they have not survived, or never existed.
Your mother matches three GEDmatch kits managed by me, but all of them (and one or two others that I recognise) are from the west of County Clare (where my grandmother was born) and have nothing to do with my grandfather's Waldron ancestors from County Roscommon.
I wondered whether the matches to the kits which I manage might be through your McInerney ancestors, as that is a very common surname in West Clare, but I see from your Ancestry pedigree chart that your McInerney ancestors were from County Limerick.
Sorry that I can't be of any more help
