Dear Celia and Mel
Thank you for your help!  Mel I'm sorry if I've confused you on dates 

.  Yes - when I went to Birkenhead Library I checked all denominations in Landican and also Flaybrick for both George and Alice's deaths but no record.
I am most keen to find anything on George's burial/obit etc.  I've just found out that he was a mason - would that have any bearing on where he was buried I wonder?  I found out by contacting his daughter's nephew who was the information on her death cert.  Luckily he was still at the same address 10 years on.  He's given me a few papers that George's daughter had but we still don't know where George is buried.  
Like you say Celia - George and Alice may have been cremated.
I also found out that George and Alice were married in a methodist church in Birkenhead but it has no graveyard etc.
Thanks again
Barbara
