An important and touching piece of family history

I transcribed a letter the other day (scroll to bottom of the page), a moving letter from a soon-to-be Father-in-law (John Beynon) to a soon-to-be Son-in-law (Benjamin Nicholas), giving his blessing to the marriage and their decision to move away from the family. This is a father, doing the right thing, but expressing a bit of regret that his daughter (Margaret Beynon) will no longer be close to him. Benjamin and Margaret ended up in America, so I'll have to check census records and maybe some other resources to see if they settled somewhere else first. This very interesting letter adds so much personality to the historical figures that we only know by birth and death dates, census records, and headstones.

p.s. Any Welsh speakers or readers want to help me with the address?
