Hi Kelly,
Your Dad's Uncle Richmond Picken is indeed on the Bo'ness War Memorial WW2 Merchant Navy Plaque.Do you have any photos of him you could share?
I'd also love to see that photo of your Dad sitting on the Sunderland.His name appears n the Bo'ness & Carriden Parishes Roll of Honour as follows:
PICKEN, RICHMOND, 6 Newtown Cottages. R.A.F. No. 1573692. Joined, October 1942.
There is an entry also for:
PICKEN, MARY K. -same address-. WAAF No. 489283. Joined, September 1943.
Do you know who she was in relation to you?
All the best,
G67
