Whelan in Rathangan Tithe Records

The Church of Ireland parish of Duncormick was united with the Parish of Ambrosetown (Lewis 1837 entry for parish of Duncormick), and that's the way it's listed on the Tithe records. The introduction pages make a note of this see pages 638 639 642 etc. There are 20 townlands mentioned but no sign of Rathangan - only certain types of agricultural land and usage were eligible for Tithe payments, so the tax may not have been applicable to any properties Rathangan townland - see listing for Ambrosetown (& Duncormick) parish. There's no sign that I can see of any Whelan entries for the parish.

Tithes were only applicable to agricultural land, and only covered eligible properties of over one acre, and did not cover towns and villages, small houses and labourers cottages etc. Certain types of land usage were excluded, but the rules were not the same in all areas, in addition some locations were Tithe-free. I checked the list of townlands included under Ambrosetown on the Tithes and it doens seem to include any from Duncormick civil parish.. and no sign that I found of any of these under other nearby parishes (some parish boundaries changed by the time of the OS mapping and Griffiths).

I see a John Whelan in the parish on Griffith's valuation - is he one of your Whelans ?
His property seems to be in the town and at that time is described as 'House & small garden'

Edit to add : the Lewis entry for Ambrosetown shows that Tithe's amount to just over £138 for the parish, which is close to the amount shown on the summary of the Tithe records - see page 655, the Lewis entry for Duncormick/Duncormuck shows the amount for that parish as just over £300 ... so the there appears to be shortfall...
