Hi
1891 census RG12 193 folio 23

Walter FitzSimons 62 Head Widower Solicitor Ireland
If the marriage didn't work out they may both for propriety's sake have put widow and widower on census entries. It would be most unusual for a widow to revert to her own name.

St George Ryder Fitzsimons and Sophie Geraldine Fitzsimons (both appear in these names on the 1891 and 1901 censuses) married in 1890 at Stoke Newington - Sophie marrying as a widow (propriety's sake again). St George Ryder Fitzsimons' father was Walter a solicitor's clerk. Both St George Ryder Fitzsimons and Sophie died in Croydon registration district.
There doesn't seem any evidence that Walter or St George Ryder/Walter Fitzsimons were in England on earlier censuses?
Army officers' records and militia records are held at The National Archives. What is mostly online is ordinary soldiers' records. If Edward Jackson Fitzsimons the soldier, was related he looks to have been a sibling or possibly a cousin not a parent.
