Hi,
Not very helpful I'm afraid, but I think that the Elizabeth Minnie HAYSOM born in Portsea in Sep Q 1881 might have died before the 1901 census,
DeathElizabeth Minnie HAYSOM Mar Q 1900 Portsea Island 2b 434
Age: 18
It would explain why she can't be found in 1901 and 1911.
I wonder if this could be Minnie?

Odd that it has Elizabeth twice, there is an Alice Victoria born Jan Q 1901 that would seem to be the 9 day old daughter looking at the 1911 census.
In 1911 Marie is now Minnie, still married (but Samuel isn't there) at 43 Gladstone Street, Portsmouth. (HAYSAM at FindMyPast).
There is this death,
DeathMinnie Elizabeth WILLIAMS Sep 1980 Portsmouth 20 0618
DOB: 28 Jan 1899
which matches a Minnie E Williams found in 1939, married but husband not there so don't know if it is James
Regards,
Daisy
