My grandfather was general manager of Osborne & Patton (Wine & Spirits Merchants) on Shipquay Street in Derry for the better part of the first half of the 20th Century. Wondering if anyone could shed some light on the background of this establishment and its owners. I have some old photos c. 1913. I was very recently in Derry and very surprised to see the painted Osborne & Patton wood facade at the front of the building. Any further historical details would be much appreciated.
