I need help verifing the WIlliam Birnie/Burney/Barney a mariner from Hull. Williann was born abt. 1780, married to Frances from Woolwich, Kent. They had 3 sons - that I know of. Robert b. 1811 (master mariner sailing out of Liverpool), James b. 1815, Henry b. 1819. All in the family were mariners. Francis was alive in the 1851 census residing at Ferries Hospital. Robert died age 80 in Liverpool. Any help with ancestors would be appreciated.
