Hello Barbara,
An 1863 marriage would be too early.
Sarah Ann (HARRISON/HENRY) ROBERTS was 24 on the 1877 passenger list (an age which fits pretty well with the age of 19 on the 1871 ROBERTS/HENRY marriage).
So the dob of Sarah Ann (HARRISON/HENRY) ROBERTS is ca 1852/3.
On one of the other threads it was suggested that the reason why the marriage took place at St Peters, Ashton under Lyne was because that was the area where George ROBERTS's presumed step-brother William DARLINGTON lived - William lived in Little Moss, Ashton under Lyne in the 1871 census. A William DARLINGTON was a witness at the ROBERTS/HENRY marriage; the other witness was Thomas TONKS who lived next door to William in the 1871.
It seems that Sarah Ann married as HENRY, her m.s. was HENRY at the birth of her first child, her m.s. was HARRISON at the birth of her next two children, and apparently her m.s. was variously HENRY or HARRISON on many Western Australian certificates.
The challenge is to find out, if possible, why Sarah Ann varied her m.s. between HENRY and HARRISON.
The likeliest 1871 census entry for Sarah Ann HARRISON/HENRY seems (because of other connexions) to be the following (transcribed HARBESON?):
1 Faulkner Square, Manchester
Elizabeth HARRISON head, widow, 49, General Servant & Warehousewoman, born Lancashire Salford
Sarah Ann HARRISON dau, unmarried, 18, waitress, b Manchester
Elizabeth HARRISON dau, 12, scholar, b Chorlton
James HARRISON son, 10, scholar, b Manchester
(Elizabeth jnr m TINKER then OPENSHAW; she has been found as TINKER in 1881 and brother James is living with her.)
However, these people (as HARRISON? as HENRY? as some other name? mistranscribed?) have not yet been found in 1861.
Finding the above family in 1861, if at all possible, seems to me to be an essential step.
Regards,
JAP
PS: It would also be useful if the HENRY family mentioned in the PS to my reply #13 could be found in the various censuses - if only to rule them out (or in!) ...
