1. I can see a 'Green, S. Martin' on the 'Blue Jacket' passenger list as well as Elizabeth, Wm. John, Anne, Mary and Catherine Douglas
2. Comment by Vicki Houlbrooke on November 5, 2009: William Douglas left Limavady, Londonderry and came to NZ in 1860 with 10 children on the 'Blue Jacket'. They stopped in Australia on the way, but settled north of Auckland, before moving to Tauranga and farming. He was instrumental in setting up the Presbyterian Church in Tauranga. William's wife Rachel followed in 1863 on board 'Gertude'. And his brother George Alexander in 1863 on 'Green Jacket'. Then a niece and 2 or 3 nephews came on the 'India' in 1875.
The more information you can give about the people you mention, the more chance there is of someone else connecting with your family.
Dates and places of births, deaths and marriages all help to place families.
Professions also help.
'My great-grandmother mother was a Douglas from Montrose' does not give many clues to follow up! But a bit of flesh on the bones makes further research possible. But if we are told who she married, what his profession was and where the children were baptised, then we can get to work.
Maybe it is time to update the information in your profile?
