Hi Hana,
I think I can help you with information on the Brownes of Islandmagee.
My father was Gordon Browne, who died in 1967. That would make John Hill Browne my great uncle.
I was aware that he had married someone called Ruth, and emigrated to Australia, but know few other details, except that he had a son called Jack who met up with my Browne uncles during WW2.
There were a lot of master mariners in the family. Andrew Brown (of Kilton Lane, Islandmagee) is the first I know of. He died at sea some time in the 1850s, leaving a widow Agnes (Nancy) Heggan (1830-1916), and two children - Samuel (1850-1912) and Agnes (1853-1909).
Samuel married Ellen Jane Hawthorne and lived at Bayview, Town Lane, Islandmagee where they had eleven children no less...
Andrew (1877-1960) - Abigail (b.1878) - Ellen Jane, called 'Nellie' on her tombstone (1879-1905) - Samuel (1883-1885) - Samuel (master mariner and my grandfather, 1885-1951) - Isabella ('Belle') (b.1881) - Arthur (another master mariner, 1886 -1931, who married Mary Kane as mentioned in a previous answer) - Agnes (1888 -1972) - Elizabeth Mary (1892-1974) - Sarah Hawthorne 'Sally' (1890-1985) - John Hill (1894 -1938).
My grandfather moved to Whitehead after marrying Charlotte Dagwell (from another seagoing family), and had four boys: Stanley (who married Primrose Wilson), Norman (born 1921, who did indeed go to Canada, but moved to New York around 1950. He is still living there, and is unmarried), Arthur (master mariner), and Gordon. Arthur died two years ago, the last Browne in Whitehead. He was unmarried.
Norman Brown from Ballylumford Power Station is no relation, although I believe the family surname was changed from Brown to Browne within the last 200 years. Also, Brown's Bay has no family connection, although I went swimming there a lot as a child!
The majority are buried in the old and new cemeteries in Islandmagee. Abigail is buried in Carrickfergus.
I'm sure we have lots more information to compare.
The old lady in the photograph is John Hill Browne's mother Ellen Jane Browne - nee Hawthorne (1849-1945), your great great grandmother.
