Hi
What a puzzle you have.

Hope I can help a little.
Think I've found your Rueben in the 1881. I see the IGI record for the marriage has Rueben's father as Henry Tibbles.
Chorleywood Bottom RG11-1440-148 page 11.
Henry Tibbles head 47 ag lab born Rickmansworth
Eliza Tibbles wife 41 born Chalfont Bucks
Alfred Hearne son 18 factory lab born Chalfont Bucks
Henry Hearne son 16 ag lab born Amersham Bucks
Ellen Hearne dau 13 born Amersham Bucks
RUBEN (sic) TIBBLES son 9 born Rickmansworth
Fanny Tibbles dau 6 born Rickmansworth
George Tibbles son 2months born Rickmansworth.
Tibbles is an old Rickmansworth name. The marriage for Henry Tibbles & Eliza Hearne is on Free BMD Sep qtr 1873 Amersham 3a 617. I haven't found a record of Rueben's birth though.

Henry is still with his parents in Chorleywood on the 1871, if you would like the details I can post them.
I'm pretty sure I have found Eliza on the 1871 albeit they are badly transcribed but the image looks to be correct.
1871 Merstham Reigate Surrey, RG10-835-45 page 17
Eliza Horne (sic) widow 30 field worker born Hammersham (sic) with her 3 children Alfred, Henry & Ellen.
Unfortunately this doesn't help with your quest to find Catherine Hall but I think I may have had a sighting of her so will do a bit more checking & get back to you.
