I found out that Matthew Lefan of Florence (Lauderdale County) AL was the brother of Francis Marion Lefan (my GGGGrandfather). We have been told that they came to N. Alabama and founded one of the first Churches of Christ that was called Mulky or Milky COC. It is also said that FM Lefan floated his sawmill down the TN river to AL and settled in Pleasant Field near Parrish AL and then Oakman AL.
As mentioned in previous post F.M. Lefan's father was Joseph and his mother was Nancy McMurtry according to his death certificate.
