Hello spidermonkey,
At one time scavenger hunts were 'along the lines of' posting anything that looked possible..

..then, whoever, would have the uneviable jobby of sorting thru once the scavenger hunt was over.
We know that Esther and Jane have all the posts that could be found via internet. They can only be found via paper. Thomas and his children from Sarah & Frances have mostly been paired up or died.
Frances and Charles on the other hand, had slipped thru any real digging.
I have every Richard from Montgomeryshire and surrounds in 1871... excluded those in 1881.. then worked back, using 1861 etc.. obviously, it's only the ones I'm able to find, there are a few missing from census, for whatever reason.
Knowing Frances Mary Ann and Charles were in Bray 1871 and both from Montgomeryshire. Any 'scavenged very thin scrap' is worth a look.
Thanks for finding that last bit and bringing it forward. I didn't get chance today.
