LDS Project Qualified?

Question

A European Radio interview I listened to yesterday revealed that the "Outlaw" Butch Cassidy ( Robert Leroy Parker -- https://www.wikitree.com/wiki/Parker-11929) was a cousin of the "Notable" naturalist & geologist Charles Robert Darwin (https://www.wikitree.com/wiki/Darwin-15). The connection as I understand  was by Butch's grandfather Robert Parker (https://www.wikitree.com/wiki/Parker-15705)  the LDS pioneer who ventured from Lancashire, England around 1847. 

A challenge now to confirm this relationship. Assistance, please would be appreciated

Robert Parker's siblings and their family followed him to Utah, although seemingly not altogether.

My question is: if these siblings and family are entries in the Familysearch.org source  Utah Mormon Pioneer Overland Travel Database, (1847-1868) is this sufficient to give the profiles the LDS pioneer's Category.

Answer 1

The Overland Travel Database is what I've been using to determine if they belong in the project or not.

I'll work on confirming the relationship.

Answer 2

Well the connection to Butch Cassidy looks pretty straight forward. It appears he was the Grandson of Robert Parker.

But the Charles Darwin connection looks like it comes from Charles' sister Marianne who married a Henry Parker, b. ca. 1788. If he can be nailed down as a brother of Robert Parker's Father Thomas, then we have a connection by marriage. Otherwise, I'm not seeing it. Am I deciphering this right? Or did I miss another plausible link?

Comments

Those are my first thoughts too. Marianne's husband Henry Parker came from Warwickshire, whereas the other Parkers seem be all Lancashire.
