Michael,
Many, many thanks for your research into this. Apologies for delay in sending my thanks (I'm a weekend researcher).
We know that in 1911 (Census) they were both in Luton (he was a boarder with her and her actual husband).
She gives birth to the 1st Child (father un-named) November 1914 in Llanelly, Wales.
I'll assume that from your info they got to Doncaster Road say 1915 whereupon she gives Birth Jan 1916 and he gets electrocuted 19 days later.
Millie has to be the forename that she was using based on the Death Notice so we can assume fairly certainly that the Millie Thomas who shows at #96 on the N/C Parliamentary Roll 1918/19 is her. The fact that she "qualified" suggests that she was still "a woman on her own who was resident"
Women 30+ would only appear in the registers after 1918,, and 21+ after 1928.
Woman over thirty who were occupiers in their own right or married to men entitled to a local government vote, were given the right to vote by the 1918 Qualification of Women Act. The Equal Franchise Act 1928 gave women equal voting rights to men.

The next time I pick her up is a further marriage in 1922 down in London when she still has the married name of Stafford although it does state under Condition "...from whom she obtained a Divorce."
Interestingly one of the Witnesses is her (spinster ?) "Step-Daughter" from the Stafford Marriage namely Ethel Grace CORNISH (born circa 1900).
Family Names differ since she was born illegitimate to Annie (no relation) Cornish and certainly appears on that Luton 1911 Census with all the others.
So, my favour to ask is, can you further search forwards from that 1918/19 Parliamentary Roll to see when Millie Thomas (Thomas or Stafford or Cornish) might have disappeared from the property ?
Many, many thanks,
