The Registry of Deeds can be searched by either surname or townland. With a common surname like Taylor the surname index is a bit of a struggle and my advice is to focus on townland
https://www.familysearch.org/search/catalog/185720?availability=Family%20History%20LibraryThe way the records are held takes a little getting used to. But basically you need to search in Antrim, in Lower Glenarm Barony, Tickmacrevan parish and townland. That’s the way the records were kept. (Early records didn’t bother with the barony)
I’d search in the townland index for any Taylors in Ballyvaddy. The indexes are in batches of years, so quite a few searches depending in how many years you want to search. If you find a Taylor In Ballyvaddy you then need to note the deed number and then look the actual deed up in the main records. If you get the hang of it first time round you will win a prize (in my opinion). If you do find a Taylor in Ballyvaddy, give me the details and I’ll try and find the actual deed for you.
I think you live in Oz. Think about all this in terms of Oz records (about which I actually know nothing). If your ancestors owned a station for many years there would probably be some paper records. But if your ancestors were farmhands who worked here and there for a year or so before moving on, there probably wouldn’t be any records now for their stay on those stations. Would that be broadly right? Well it’d be the same in Ireland. Labourers would be on “at will” leases where either side could give notice at any time (and where there was rarely a written contract). Though it carried the risk of eviction without notice, it generally suited labourers as they could move to another townland to take advantage of unexpected work opportunities there. No notice was required. Paper records rarely existed for labourers/weavers in Ireland in the 1700s or early 1800s.
When your ancestors arrived in Oz what were they then? If they were farmers/station owners then they might have been that in Ireland (if they had the capital to get a station in Oz). But if they were labourers or farm workers then they were probably that in Ireland too. Does that help?
