John Taylor of Altibrian died in 1880 aged 84. The informant was John Taylor of the same townland.
Wife Jane died in 1877 aged 81:
The Valuation Revision records on the PRONI website show the farm (plot 12, a 21 acre farm) passing to Samuel Taylor in 1881. In turn he was replaced in 1893 by William Kennedy. In 1901 there were no Taylors living in the townland:
If you are looking to find other descendants of John Taylor you would need to provide a bit more information as to who they may have been as it seems they had evidently all scattered by 1901.
I checked the 1831 census for the townland but there were no Taylors there then, so they appear to have arrived between 1831 and 1859 (Griffiths Valuation).
This looks to Samuel’s marriage in 1858. Who else are you looking for? (It’s a common name and so hard to search the records).
