Back in the the Sixtys Dad was called to be a Seventy. That was when Seventy's were Stake Missionaries rather than General Authorities as we know them today.
Not sure about the first letter, but this one is from a Frank M. Moxon who claims to be a half Brother to Milton Albrecht the brother of my Grandmother Mary Magdalene Albrecht. The letter refers to the possibility that both were desended from the Habsburg royal line. Theres some possibility of there not being a connection in the Albrecht/Burrows line to royality, but who knows. I plan on researching more in depth.
