Hi 
I am trying to trace more information on my Gt-Gt-Gt Grandfather Samuel Jamieson.  We know he was born 25.7.1821 in Ireland - Father James & Mother Agness.  He married Maria Scott 05.01.1849 in Maghera, Londonderry.  They moved to Scotland & we have census records for 1851 and they sailed to NZ and arrived in 1863 on board 'Captain Cook'.
I would like to find more of the family in Ireland, brother's/sister's, etc. and also his Mother's maiden name.
Would appreciate any help.
Thanks
