One other idea, not that I planned it but it broke a 10 year old brick wall.
When researching other people keep your eyes open for the names of your brick wall person. No matter how unlikely it seems.
While looking for GGGP on my mothers side, on a rather obscure website, I saw further down the page 'George Ross' and decided I'll take a look even though I was quite sure it wouldn't be the George Ross, I and 3 other cousins had been searching for, for 10 years.
But it was the right person, it took a long time to check everything, including a phone call from Canada to England. And £10 to get an emailed pdf of the record.
The only connection to the town that had the record was a very suspect place of birth on a census. It turned out to be correct.
