I have discovered that Luther Henry Tatham, a grandson of my 5x great grandparents was a patient at the Royal Albert Institution in Lancaster at the time of the 1911 census.
I have found out that the institution cared for 'idiots' and 'imbeciles' - people with severe intellectual impairment.
I would like to find out when he was admitted there and what was wrong with him. He died in 1920 aged 32 and I suspect that he was still there then.
Thanks.
