Rosinish, Sorry I have been so long in answering your questions.
1. John Gibson born 1804 died in Tasmania in 1879 when only the country of birth was required.
2. He married Mary Brown, daughter of Andrew Brown and Janet Shields, on 14 November 1828 - Dundonald.
3. John made a list of his children - 8 in total, but only three made it to Australia. The missing 5 are not mentioned in his will.
3. Of the 8 children I have found 3 in ScotlandsPeople, and 1 from a NZ death certificate.
So here they are:
John - born 9 November 1829 in Irvine, baptism 15 November 1829 (I'm sure this is from SP but I cannot find it at the moment)
Andrew - "son of John Gibson and Mary Brown spouses Halfway Street was born 22 June and baptised 10th July 1831". (This from the Dundonald Register)
William - no record of birth or death found
William - "" "" "" "" "" " ""
Mary - 10 July 1838 - this from her death certificate in NZ
James - "John Gibson Seaman and Mary Brown a law son James born 10 August . Witnesses John Gibson and John Dunlop" from Parish of Glasgow, Births and Baptisms, 12 August 1840.
Eleanor - no record of birth or death found
Andrew William - "" "" "" "" ""
Hope you can make some sense of all this and tell me what you think the names of John Gibson snr should be.
Regards
Jean
