My grandpa was from the last generation of Geordie sailors. He was an engineer for the merchant navy, hence the great uniform. Gran stayed home and cared for my mom and her siblings while grandpa was out sailing. He once showed me a map of all the voyages he had been on, and i wish i knew what happened to it.
He would have been 92 next month, so my guess would be he is mid 20's in this picture. I'm not sure what year they got married. Living through the Blitz in a strategically important city will do that to you. Grandpa told me a story about how his dad (on the left) had severe shell shock and would refuse to go into their bomb shelter in the back garden. He would make aure the family was safe in there, and them stand outside and watch the planes. My other great-grandfather on the right got an accomodation for helping a wounded Canadian officer get off some beach in WW2, i wish i remembered which one. Those old Geordies lived through some serious shit.
