I am researching the Tiernan family and I know that Joseph Tiernan, my great grand father, worked as a tug captain for John Dalton on Newcastle harbour in approx 1870-84. I am wondering if anyone has come across Joseph whilst looking at the Dalton family. Joseph was listed as a master mariner when he died. I am particularly interested in any info to do wth Joseph's employment with John Daltons Tugs Thank you henry
