hi revereidlehands,
I did make more progress with this. The information posted by Devon Maid on 7th June showing Elizabeth Collings and James Moore senior married on 27th Sept 1821 in Maker just over the county boundary in Maker, Cornwall is correct. I found a transcription on FindMyPast which confirmed this, I have not seen the actual image, but it all seems right to me.
I dont think Elizabeth came from Kingsbridge, I know it says that on the 1851 census, but suspect that may be incorrect. 1861 census has her birth place as Devonport and 1871 census has Stoke Damerel. On FindMyPast I did find a probable baptism record for Elizabeth dated 24 June 1791, parents Joseph and Christian Collings, location, Plymouth, Charles the Martyr Anglican church.
I also purchased the naval service record of James Moore junior (Edwin's brother) from The National Archives which confirmed his date of birth as 29 Sept 1835 and shows the ships he served on up to 1873. I can send you the file privately if you wish.
I did not manage to find a baptism record for James which was what I originally was looking for when I posted, but thanks to extra research and the help of others here, I made good further progress and was happy with the info I found.
About a year ago, I went to TNA Kew and found the Greenwich Hospital School admission papers for several of my own naval ancestors which really helped me with my paternal line.
Best Wishes, Phil.
