Brian, I've got a different solution, going back from Gt Uncle Fred Lawson who married Eunice Margaret Looney in 1900:-
Thomas Looney (bc 22Nov1815 Mau, parents Christopher & Eliz Kneale) married Mgt Shimmin 12 Jan 1839, BUT on 9th Oct 1837 a Thomas Shimmin was c @ Ramsey. parents Mgt Shimmin & Thos Looney. In 1841 in Lonan Margaret Looney (25) had sons Thomas (3w, should be 3y?) and Christopher (1y); no Thos snr (fishing?). Margaret als Shimmin died in 1844 and Thomas married Mary Ann Kelly. In 1851 they had Thomas (13y), Chistopher (12y) William (5) and John (3). In 1861 Thomas jnr (23) was at 27 Gretch veg with 1st wife Jane Eliz Caine and Thomas snr was at 24 Gretch veg. Thomas jnr then went on to marry Ann Jane Looney and Eunice Christian Callow.
In 1891 Eunice Margaret Looney was living with her aunt Mary Ann Emily Cleator als Looney (Thomas snr's daughter, mentioned in his will of 1884)
Does this make sense? - it's quite possible I've got totally mixed up!
