Help for Harper Family from Sheffield England from 1870 S Back Ernest Harper Born 1875 Burslem Sheffield Married Florence Birkinshaw Born 1877...

I don't have anything more for Ernest Harper's Dad apart from his name was Robert Harper and he was born in 1852 and died in 1893. I do know he married Martha Turner. But that is where it stops. Some help to get further information on any of the above would be appreciated. I am Ernest Harpers Great Great Grandaughter.
