Scoosh and Carol
Your input and interest much appreciated. Thank you.
Carol I actually have a copy of the original Certificate of Registration for the Aldergrove from the UK National Archives. The vessel met an unfortunate demise off the coast of Peru in 1905.
My grandmother's middle name was Sommerville and she always said they and the Sommerville family were cousins some of whom visited as seafarers on ships calling at Port Chalmers in Dunedin. Her father worked as a fitter in a big ship building yard at Port Glasgow before immigration to New Zealand.
Likewise I never discovered when Robert G Sommerville died .... can anyone assist in that regard please? I note he became Provost of Port Glasgow in 1877.
