the burial reg entry is definitely Frangagh not Trangagh (checked on photocopy at museum - original reg is back with parish)

Wm Garrett french is noted for 8d in Alchest treen in 1740 lib assed with indication that a change went thru in May 1746; the 1750 book shows Wm Carrett junr holding same rent
the 1761 also shows Wm Carrett junr but with a change in Oct 1764;
consulting lib vas May 1746 Wm Carrett french drawn + Wm Carrett his son entered as right tenant
Oct 1764 William Garrett junr drawn and Wm Garret his son entered (there is also intack 160 with same transfer 'entered as before'

The 1764 will is a deed of gift (=NSS May 1760 23) dated 3 Mar 1759; Wm Garrett(Andreas) gives to friends Daniel Cowll + wife Caterin als Garrett a parcel of intack part of Killip's Close rent 4.75d;Witt Jon Radcliffe x, Philip Radcliff - as will Danl Cowll sworn admr

I forgot to look out the 1746 decree of a Wm Garrett in Lezayre which is probably that of Wm Garrett french (whatever that refers to) - George Broderck does not appear to treat this name
