Muckle, Thomas

I'm seeking any information available on Thomas Muckle, born in Millisle in 1832.  He married Agnes Magill (McGill) in 1853 in Millisle.  Agnes was born in 1834 in Millisle.  Her father was named John Magill.  Thomas' church records show he was a farmer in Ballycopeland.  They were Presbytarian and Elizabeth Cree was a witness to their marriage.  I can't find any death information for Thomas and Agnes.  There is a Thomas Muckle listed on Thomas and Agnes's marriage record as father.  He's also listed as a farmer.  This Thomas (the father) also has a brother called James.

I know of five children Sarah b.1865, Elizabeth b.1867, Jane b.1869, John b.1873 and Hugh b.1854.  All were born in Donaghadee except Hugh who was born in Belfast.  I think there are likely more children given the gap between Hugh and Sarah, but haven't found any.  I'm a direct decendent of Hugh whop emigrated to New Zealand in 1875.

There are a lot of Muckles in the area of Donaghadee and their names seem to go back quite far, but I can't link any of them up.  Can anybody help please?  I'm particularly interested in Thomas Muckle and tracing him back further.  Thanks!
