Thanks IBarwise

Again we appreciate it.
We received the marriage certificate today from John Thomas Miller and Margaret Barwise. We need a little help now with the Miller line.
24 Aug. 1913 the marriage took place. The father of John Thomas Miller is shown as Henry Miller, Dock Labourer. John Thomas was 24 y.o. at the time, bachelor, stoker Royal Navy living at 51a Skirving St., Liverpool. Margaret Barwise was shown as 22 y.o., spinster, Labeller in Bottling Stores, living at 8 Skirving St., Liverpool, George Barwise (Publician) was her father and is shown as deceased. They were married at St. Anthony's Church according to the Rites and Ceremonies of the Roman Catholics. St. Anthony's Church is shown as Scotland Road, Liverpool, county of Liverpool.
Is there any way of tracing the great grandfather Henry Miller??? That's the first we've heard of that name.
Thanks,
Glenda
