Hello Greg, Several generations of my grandmother's people attended the Baptist Lower Meeting House in Amersham. I'd be interested in having a look at your Nash Minute Book, please ... I image there'd be little difference in practices between branches! In your fourth paragraph you ask "how common was this term?". I presume you mean the terms Brother and Sister? I don't know whether 1892 and 1944 are relevant, but religious communities still use these terms when referring to fellow-parishioners. At the Family History Library in Salt Lake City a few months ago, church members used these terms when speaking to or talking about fellow Mormons. My husband and I also have letters written at the end of the 1800s to our emigrant families in NZ by members of their "home" churches. These friends/church members, although not related, used these terms for the emigrants, to refer to other church members back home, and also to themselves when they signed the letters.
