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).

As per a transcription on RootsIreland, brothers Samuel and Thomas Taylor were baptized in the Presbyterian church on the same day in 1842. Parents were Jane Taylor, John Taylor. Home: Altibrian .

That is really fantastic extra information for my tree - what happened with Thomas do you know? I would like Jane Taylor's maiden name as Samuel's death certificate states mother as Jane McLeah though the name McAleese has been given to my great grandfather's daughter and Samuel's son Samuel McAleese. I realise John Taylor is a common name to check where I have no other reference. Thank you for your prompt assistance, very appreciative of it.

I had a look for a marriage for Thomas Taylor in the Dunboe area 1860 – 1890 but did not find one. Nor was there a Thomas Taylor aged c 58 born Co. Derry anywhere in Ireland in the 1901 Irish census. So possibly he left Ireland for work elsewhere. (As so many others did).

To find Thomas’s parents you would need to search church records for their marriage.  Tradition was to marry in the bride’s church, so not necessarily the same church where children were later baptised.

According to the PRONI catalogue Dunboe 1st Presbyterian has the following records:

Baptisms, 1805-12, 1825-6 and 1843-1949; marriages, 1845-1934; session and committee minutes, 1828, 1841-54 and 1859; male communicants, 1826-66; list of the poor, 1830; seatholders’ account book, 1853-65; receipt and expenditure book, 1847-72.

Dunboe 2nd has: 

Baptisms, 1864-1983; marriages, 1845-1913; session minutes, including entries for baptisms, marriages and communicants, 1835-68; stipend book, 1894-1951; details about persons emigrating, 1841-7 and 1866.

The Church of Ireland has 3 churches in the parish. 2 lost all their early records in the 1922 fire. Only Dunboe has any records for the period you need:

Baptisms, 1839-1982; marriages, 1845-1974; burials, 1845-1982; vestry minutes, 1783-1864 and 1920-32; general vestry register, 1920-82.

Some of these Church of Ireland records are on the rootsireland site. 

Another source you might find helpful is “Heath, Hearth & Heart” by Alison McCaughan, published in 1988. ISBN 10:0951392204.  It’s a detailed history of many of the families connected with Dunboe 1st Presbyterian church and goes back earlier than the church records do.

Thank you for your prompt assistance and will keep you informed of any positive information .
