Now that's strange. I put her mum's name in again with just year of birth and Sheffield ( this is exactly what I had done before but this time I got a result. Well 3 to be exact but 2 weren't the right person and Vera is living there as Vera Harrison. So I tried Nicholas again and got 4 results. He is living with a work mate I think as they are both locomotive firemen, in Cartmell Road about 200 yards away.
I think there must have been a problem with the site before as now it's giving me all these options whereas before it just kept saying No Results Found to everything I put in.
