Thanks, I have this record.
There is only one Anthony Proudlock birth registration in Co Durham in the 1870's so it has to be him, whether he went from coal miner to sailor/tailor or soldier
I think his father John is in Trimdon in 1901 but wife is down as Margaret and should be Mary Ann, and daughter Margaret Jane 1884 is down as Mary J but the writing is not v. Clear.
I will see if any sailing Anthony's turn up, but that's a job for tomorrow.
