Thanks for you messages so far. I mainly need assistance with the Irish roots rather than the Scottish. I have the following dates:
John Scullion (1832?-1906) born Ireland, married Mary Joiner (also spelt Junor/Junnor/Joyner/Jenner) (1831-1891) in 1854 in New Kilpatrick. Mary was born in Maryhill, Glasgow.
John Judge (1822?-1883) came from Sligo, Ireland according to his marriage record. He married Mary Walls (1822?-1861) in 1838 in Barony, Lanarkshire. Mary was also from Sligo (from marriage record).
Hugh Scullion (1811?-) came from Ireland. An ancestry.com family tree suggested Derrykeighan but judging from the comment about that here, it is most probably incorrect. He married Sarah McLean (1811?-1885) possibly around 1830ish.
Charles Joiner (1800?-died before 1841?) married Margaret Bowman (1801?- died after 1871?) possibly around the early 1820s. Margaret is from Ireland, not sure about Charles.
Peter walls (1776- died after 1861) from Skerries, County Dublin married Mary Roman (1793?-1867?) possibly in the early 1820s.
John Judge (1780?-) from Ireland, married Alice Kelly (1780?-) also from Ireland probably around 1825ish.
I would love to know where I can find out more about them as I am in Australia.
