Hello again Geoff. Regarding the online Cahir RC Baptism registers I've double-checked the IFHS ones I had for Mary (7 Apr 1867) and John (17 Jun 1872). The IFHS and LDS versions definitely seem to have some differences, and not just with the mother's first name. So maybe the IFHS/LDS records are from civil birth records, not RC baptism registers?
Reference: Microfilm 02460 / 01 : Baptisms 1 Jan 1845 to 28 Dec 1880,p146 and p170
(the 2nd from bottom set of microfilm here
http://registers.nli.ie/parishes/1097 ,210 pages).
About halfway down p146 (Mar 1867 to May 1867)
http://registers.nli.ie/registers/vtls000632137#page/146/mode/1up is what appears to be Mary's record. The date is 10th (not 7th) and the name is Mariam (not Mary), parents appear to be Edmund Purtill and Johanna (definitely not Judith) Sweeney address Market St. Here's my reading of the line (bits are very feint and hard to see):
10 (Apr 1867), Mariam, Edmond Purtil et Johanna Sweeny, Market St, et Ellena , The very bottom of p170 (Apr 1872 to June 1872)
http://registers.nli.ie/registers/vtls000632137#page/170/mode/1up is badly scanned and I can't see date or child's name, but I'm fairly sure that the very last line gives parents Edmund Purtill + Johanna Sweeney address Market St (not Wellington St). Here's my reading of that last line (note: I just increased the contrast and the child's name jumped out as Thomas, but I'm not sure that's right:
, Thomas, Edmundum Purtill et Johanna Sweeney, Market St, Thomas Hippoll et , Second entry on p135 (Sep 1864 to Nov 1864)
http://registers.nli.ie/registers/vtls000632137#page/135/mode/1up appears to be the Edmund Purtell (31Aug 1864) from IFHS/LDS. Here's how I read that entry:
4 (Sep 1864), Edmundum Purtell, Edmund et Joanna Sweeny, Market St, Michael Glace et Ellen Sullivan,M MaceyTwo thirds down p156 (Apr 1869 to Jul 1869)
http://registers.nli.ie/registers/vtls000632137#page/156/mode/1up , a couple of lines above the crossed out one seems to be Ellen (1Jun 1869) from the IFHS record:
6 (Jun 1869),Ellenam, edmund Purtell et Johanna Sweeney, Market St, Larbo Harries et Hanna Linan,R Cnixerferth(obviously the sponsors' and clergyman's names are misread on my part, but that's the best I can do)
I recall reading somewhere that the RC clergy liked recording things in Latin and they often slung an '-um' onto the end of the child's name. So the 'Mariam' was probably actually just MaryI've started a new topic on the Handwriting Deciphering forum to try and get the best reading of these lines - Cahir RC Parish Records - 5 Baptism records I'm trying to read
