Wow. A big thank you, Margot. That is really interesting about the twins. Thank you too for clearing up about the Portland Church. The Baptism that I could see in 1831 was for, I thought, Thomas (but the date seems long after his supposed birth date (see these lower down). Joseph was my grandfather (my father didnt marry until he was in his fifties!)
The (incomplete) copy of the 1851 census for the family family shows the parents Anthony as aged 54 and Mary aged 48 (her NZ obituary implies her age would have actually been 49 or 50 years, not 48) and that they married in 1820. There were twelve children in the census of which two were shown as being married. I believe Anthony died around 1869 because late that year Mary, (with her age written down by about 20 years), sailed to NZ with her then adult sons William and Joseph. She died here in NZ in 1888.
With your kind help it looks like we may have uncovered all12 of the family. It would appear I might be a bit 'out' on some of their birth dates. Maybe some of 'my' Carroll christian names may also show up in official Baptism records. The children collectively identified are;
Catherine (Kitty) b.1825 d.1914 (Melbourne, Australia) She married a Daniel Madden, I assume in Australia.
Thomas b,1929; d.1896 (NZ). Emigrated to NZ in 1861
James b.1832; d.1897 (Queensland, Australia) Emigrated with brother Michael in 1865)
Mary b.c1833; d.1920 (Melbourne, Australia)
Edward b.1835? d.1932 (NZ) (The birth date I have for Edward looks like it should actually be for Michael from your official records. My date was taken from his NZ obituary but maybe no-one in NZ really knew when he was born.) Emigrated to NZ in 1863.
Michael b.1835 d. 1923 {Melbourne, Australia). (Birth date 1835 from your official records)
Anthony and Joan b.1837
Timothy 1843
William b.c1838; d 1912 (NZ)
Margaret b.1846; d1913 (NZ). Married a John Duncan.
Joseph b.1849; d.1926 (NZ)
The Carroll tenant 20 acre farm at Little Portland was located just over the fence from the current goat farm. Only a few stones remain of the house but the adjacent large chestnut tree that was drawn in the Griffith Survey map of the Little Portland area is still standing. The mother, Mary Carroll was Mary Kirwin (or Kirwan) before her marriage. I see a refernce to a Michael Kirwan as having a house in Lorrha in the Griffith survey. Her father possibly, given Michael is a Carroll family name?
Many thanks, for your help, Margot
