Sorry, yes this is John baptised in 1813. I have looked at Hewelsfield churchyard but he is not there.

Sorry that I cannot directly help , however an avenue to research might be the Seamans Mission - The Bristol Channel ports were " in at the start" of this movement in the 1840's.

The service may have been held at St Peter's Church

NEWPORT, MONMOUTHSHIRE.

This rapidly increasing port demands great efforts on behalf of seamen. Its shipping trade is carried on by means of the old dock here and the new Alexandra Docks, and also through many coasters at the wharves on the river Usk, whose crews spend much of their time on shore. 335 vessels visited Newport from foreign parts in 1876, 1,391 coasters, and 7,661 vessels of other kinds, sailing-vessels chiefly frequenting the old dock and steamers the Alexandra Dock, which are about a mile apart. Seamen lodge in the parishes of Holy Trinity and St. Paul. There is plenty of room for their accommodation in Holy Trinity church, and in a very small chapel especially built for their use by the late rector in 1870 at the pier-head, but only a few attend either of these places of worship. The present rector of Holy Trinity is an honorary chaplain of the Missions to Seamen Society, which supplies a scripture reader for the use of Newport. The latter holds a license from the bishop, and conducts divine service in the pier chapel on Sunday afternoons, and also once a week in the evening. He also does all in his power to persuade seamen to attend divine service at other times; but one clergyman with a resident population of 3,000 people to attend to, and one scripture reader, are a very insufficient staff to minister to a large body of seamen as well as to a considerable general population, and we trust that before long vigorous efforts will be made to follow the excellent example of Cardiff in the same diocese, in providing sufficient spiritual help for the seamen of Newport. It should at once have the help of a chaplain and another scripture reader at least; a small chapel having a large vestry-room attached to it, to serve as a seamen's reading-room, should be built near the Alexandra docks; and the present very small chapel at the old dock should be exchanged for a similar chapel and reading-room there. With such means much might be done for seamen here, and is most urgently needed.

The crews of steamers might be carefully visited at convenient times, and those of sailing vessels, often in docks for several weeks, might be very effectually benefited by services held on board, and the distribution of books. At present there is no sailor's home, nor any reading-room where the one only scripture-reader could give counsel to seamen, and help them, so that very much requires to be done here for the spiritual advantage of seamen.

Intercession is made in church for those at sea during stormy weather, but prayer also is needed in behalf of those in harbour at Newport, that it may please God to provide sufficient means of grace for them.

I have tried to find John's widow Louisa thinking that they would be buried together - she died in Newport. I have now covered every cemetery in Newport without finding either of them (or their children).

According to Gloucester Archives the printed MIs for the Moravian Church have only Ann Syner buried here in 1886 - not sure who she is!
