Oh dear
Liverpool Sarah is not the child of Charles Higham and Ellen Taylor.
If you do your searching correctly, (I told you it is on Lancashire OPC) there is one entry for a Sarah Ellen Hyam, baptised on I think it is the 15th of February, 1865. Her parents names, I quote, are Charles Hyam ( NOT Higham) and Ellen Hyam.
They are residents of Liverpool, and Charles' occupation is a Coppersmith.
So Charles Hyam born in 1825, would be almost 40 years old.
The Hyam name is not misspelt in Sarah's Baptism entry/ record.
Linda, go to Lancashire OPC website, and find the entry. When you get the list of parishes, click St Peter's, then the year 1865. Then scroll to February. You'll see it.
I have another genealogy site that showed me an article where the two children are living in St Pancras in 1881.
These two facts I know. I wouldn't waste time keep looking for other Charles and Ellens that aren't the right couple.
