John Porteous, b Ireland c. 1808, a brass founder, married Mary Hickey (born the same, my (?)gt-gt-gt-gt-aunt) and came to live in Salford , near Manchester , Lancashire, England, by 1834.
In 1851, in Salford, they had three surviving children living at home: John, born c. 1836, a brass founder in 1851, William, born 1837, a plumber in 1851, and Isabella, born 1839.
After 1851 I have not been able to find any trace of the family.
Can anyone help please?
