Hi,
No I not related, just trying to help. At the moment I cannot find a birth for your William Heatlie Campbell in Lancashire.
This is the 1851 census for Heatley Campbell:
Bond Street, Liverpool
Heatly Campbell, Head, Married, 24, Cooper, born Ireland
Ann, Wife, Married, 21, Ireland
Michael, Son, 2, Liverpool
Catherine, Daughter, 10 months, Liverpool
Ann Downey, Widow, 40, Char Woman, Ireland
So no son William. I was wondering if William was perhaps a nephew? I just can`t pinpoint him in any census.
