forgot to mention Julia's surname looks like being Butt - thanks

Hi Avolon, welcome to the forum.
I'm from Cinderford but don't recall ever seeing or reading the HIGHLEY / HIGHLY surname before, altho' BUTT and RUCK are less rare as far as I recall.

Have you searched this site's Parish Records database ?. (See dropdown menu under "Resources" in main toolbar).

There are actually abt 200 HIGHLEY PRs, the vast majority are western Forest especially Monmouth area.
Always worth searching this forum for prior threads, but in this case only a few mention the HIGHLEY name, and they seem to all be Monmouth area.
eg see https://forum.forest-of-dean.net/index.php?id=8938

I can only see one Mark, he's also the only one in Cinderford, think he's yours;

Searching FreeBMD, to my surprise there are only seven ! results for the whole UK, 1837 until now !!. All bar one are in Halifax West Yorkshire, so gives a suggestion the HIGHLEY surname may originate there ?? (lots coal mining there so quite possibly a link if true).

This is the only local hit, but is he your Mark, did he marry again late in life, or is it a son ??;

Using GlosBMD searching Mark Highley in 1912 can confirm;

So that's a good reason we didn't find this in the Church aka Parish Records, as was at the local Registry Office.
This record shows that this was the bride's second marriage, her maiden name at birth was Mary BRADLEY, her first husband was a BROWN.

Re-searching FreeBMD and then the FoD PRs show a great many more records for Mary Highleys thro the decades. Again mostly are in Halifax area, but this one looks like maybe our lady.

Note the same Register Reference as for Mark's burial earlier, suggesting this maybe an actual Plot number in the graveyard.

Once again can search for her earlier marriage to a BRADLEY;

So Mary Bradley now Brown was born abt 1860, which perfectly matches the earlier Burial record, and she's "from" the Cinderford area like Mark.

Cannot find her Baptism in the PRs, but this seems to be her, again from FreeBMD & then GlosBMS confirming her mother's maiden name;

Husband Job Brown died in 1911, so a good fit for her second marriage to Mark Highley in late 1912.

Least that's one theory re Mark Highley's later life, but it needs to be compared with the census info to see if I've got it right.
That would also prove, or not, if Mark was a miner. I've searched this site's Freeminer database but no luck there.
