Hi Dan,

The ever-helpfull and quick-to-search GlosBMD site has the following Records which fit your case;

Birth Details

Child Surname Child Forename Father Surname Mother Surname Mother's Former Name Year District Office Register Entry
DAVIS Russell George DAVIS DAVIS BULLOCK 1890 Gloucester Gloucester, Huntley 18 143

(Bullock is a wellknown Longhope family name)

and

Marriage Details

Groom Surname Groom Forename Bride Surname Bride Forename District Parish Building Year Register Entry
DAVIS Russell George HOOK Emily Ambury Forest of Dean Longhope All Saints 1926 1 380

I wonder if Russell's middle name "George" could possibly be a transcript error, or ???
Interestingly Eliza's middlename is the unusual Ambury, as per this thread's original poster..?

Again searching GlosBMD, for a Davis/Bullock marriage, gives this good fit, the earlier posts show Russell's parents were Jabez & Sarah Davies;

Groom Surname Groom Forename Bride Surname Bride Forename District Parish Building Year Register Entry
DAVIS Jabez BULLOCK Sarah Jane Forest of Dean Westbury-on-Severn (FoD) Register Office 1884 7 152

==============================

Dan,
I see Ambury's name is still displayed as blue, hence "active", altho clicking on it suggests they've not visited the forum since 2012. I suggest you mail Ambury direct bu clicking their username, they'll hopefully get your email and may be able to help clarify things further.
Have you seen the excellent Longhope Village website ?. I see it contains photos of Jabez and Sarah's grave, both lived long lives 'til about age 90, and hopefully the site will provide much more of interest to you.

Hoping this helps, Jeff.
