Hi Ian
I got sidetracked onto your James Cathcart of Kendal and wondered about these two
Cathcart of Kendal as being possible brother and sister and perhaps connected to your James Cathcart of Kendal
George Cathcart b 1855 ? location d 1st qter 1888 Kendal Westmorland source freebmds
Anne Cathcart b 3rdqter 1865 Kendal Westmorland Mother's Maiden Name Dickinson?
is living with the Jackson family in Church St Lancaster l881 census as a general servant in 1901 a domestic servant with the Rev William Ewald C of E with a housekeeper, in 1911 with William Harris Ewald Kendal Westmorland b 1841 Leghorn Italy Clergyman Established Church Vicar Of St John Lancaster all living at vicarage.
a few other records
a John Cathcart m a Jane Dickinson in 2nd qter 1853 Preston Lancashire source freebmds
a John Cathcart b 1825 d 1885 Lancaster freebmds
a John Cathcart b 1831 Ireland is a widower coachman living as a boarder with James Thornton another coachman in Windmill st Lancaster 1881 census
So we have a possible connection between Kendal, Lancaster, and Ireland 1831
but I have nothing to connect to James Cathcart b 1800 Ireland other than Northumberland census 1861 etc
So now I am changing back to James Cathcart b 1800 irish events say 1814 until he moves to England before 1840 the most likely about being a barrister etc in Dublin Hallmarks contribution is so close. If you or he are members of the free library you can look Alumni dublinenses: 1924 for free otherwise its join

I have a list of 37 Cathcarts in the Tithes Applotment Books 1823-1837
based upon the work of the Irish Genealogy Hub’s listing for each parish in Northern Ireland, which are quicker to lookup if you know the parish! they are simple one line entries
The relevant original books are in the Public Record Office of Northern Ireland (PRONI) Belfast. in Dublin they are online in detail for the 26 counties but just one entry under Cathcart for a John in Ramelton 1834, and 8 under Catheart see
