Walter Ernest Senior

[Siely]

Alice Spinks as a witness at the marriage of Dorothy May Morris in 1919 to Walter Ernest Senior.

Is this Alice Spinks related to Jimmy Spinks leader of the Hoxton Mob ?

[CaroleW]

Look up  "Jimmy Spinks of the Hoxton Mob" on censuses & determine whether he had a sister Alice.  Use the 1921 census to compare her details with the one who married Morris

I note you have removed  details from your post above but shown them below??

[Siely]

Alice Spinks married Johnny Morris and lived at 34 Hobbs Place, Hoxton when Johnny was 42.

(not the Johnny Morris of Animal Magic TV programme)

Buy the Alice Spinks marriage cert & establish who her father was then compare it to "Jimmy Spinks" father

What is your connection to these people?

[Siely]

My connection is that one of the other witnesses at marriage of Walter & Dorothy is in my family.

What is Walter's occupation ?

[CaroleW]

So you have no actual connection to Spinks?

"Johnny Morris"  Please ensure you give the name they married as - in this case John W Morris

The marriage was 1920 so look them up on the 1921 census to establish her details then check earlier censuses for the names of her siblings

"what is Walters occupation"

If you know the names of the witnesses you must know what Walters occupation was as you must have seen the marriage cert

The Spinks/Morris marriage cert is available on Ancestry

Okay I closed my ancestry account because of a series of silly hints to very high ranking titled people.

Ancestry hints are just that - hints.  It's up to the user to decide whether they are relevant.  You could subscribe to Find My Past if you are unhappy with Ancestry

As Alice Spinks was simply a witness & has no actual connection to your FH you will find most public libraries have free Ancestry access so you can research her FH yourself & see if she is connected to the Hoxton Mobster

As you are already aware - all census info is free on Family Search
