Hello everyone,
I'm looking for help getting information about John Crowe and Agnes Anderson who travelled to Australia on the Briton arriving in June 1844.
I know alot about their history after their arrival in Australia (briefly, after arriving John worked for a Lt Caswell in Port Stephens as a gardener but eventually ended up in Bethungra, NSW). I'm hoping someone will be able to help with their history in Ireland

What I know that might assist is from immigration and death records:
John Crowe
Native Place: Belfast / Antrim
Calling: Gardener/Ag Labourer
Birth: Abt 1822 - 23
Parents: John and Mary - "Land Steward"
He and Agnes are married according to immigration records from 1844
Agnes Anderson
Native Place: Belfast / Antrim
Calling: Farm servant/ Domestic servant
Birth: Abt 1823
Parents: John and Barbara Anderson
They had no children of their own when they arrived but a notation on John's page of the ship's immigration record under remarks states "Margaret Logan, Neighbour's daughter". Margaret Logan is on board from Antrim aged 18 (parents William and Mary) and documents state she was under John Crowe's protection.
The following appear to have been referees for John and Agnes' application:
Rev Edward T Martin (Present ministry, Dundonald)
Robert Little M.D. of Belfast
John M Hastell of 46 High St
Hugh White of 16 Rupel St
Wm M Relvey of 2 Cath. Street North ?? - not easy to read I think probably is William M Relvey, 2 Cathedral St, North
John Kugler/Kugles/Rugler/Rugles of Carrowreagh - former employer
I can't find any likely birth or marriage records.
Many thanks in advance.
