I've had no luck finding one particular older person who I KNOW was alive and most likely living in greater Manchester. I've looked all whichaways and still come up short:
George LAMB, born c.1838-42, Leeds or Hunslet, Yorkshire
occupation: boilermaker
In 1901 he was living on Parker Street in Bradford, Manchester
He died in 1914 at 80 Howarth Street, Bradford, Manchester
The thing is, I found his wife, Ann LAMB, living in Ardwick with her daughter, Harriet, son in law (John William JERVIS, head), grandson, and a mystery child, who was possibly a granddaughter (I haven't bought the page yet, being "between" credit cards).
Family legend - heard almost 30 years ago - had it that Ann left George, who was an apparently brutal man, so he could be anywhere, but I assumed he'd be in the Bradford area. I haven't found him with his other three daughters, either.
Be warned: there's a George LAMB of correct-ish age and birthplace living in Ecclesall Bierlow (Sheffield), but he died in 1916 and is not mine.
