Hello Heywood and Mirf,
I owe you both an apology!

I gave you duff details.

Instead of using a calculator I did some maths in my aging grey head and got it wrong.

I kept feeding in Henry's birthdate as 1841 and it was 1851! Shame on me, I never thought I'd get a simple sum wrong. In mitigation I did find him in Ancestry in 1911! Unbelievable, I thought 1911 was a no go.
Thank you both once again,

Rossolad
