Bear in mind that if the year of birth has been mistranscribed, there will be redacted records which shouldn't be redacted, and vice versa. This would make some households appear confusing!
I couldn't find my grandmother, so I put in her date of birth. She still didn't appear in the search results, but her son did. He was born in the 1920s, and died after 1991, so he shouldn't show up. Looks like their birthdates got transposed.
I'm not getting the second name now, although I did for a little while a couple of days back.
It's really not worth my while pursuing this now, it's too difficult to find people and all too often the ones I want to know about will be redacted, even though they are long dead.
So FindMyPast won't be getting any of my money.
