After seeing multiple forms of Ancestry.com, shorter and longer, and being too lazy to write out the longer forms, I thought it might be useful to have an agreed list for RM forum users of abbreviations for the more common names we use. I'm in no way trying to tell people what to use. Anyone can write them any way they like. But if someone is wondering what a good shortcut would be, here's a suggested list.
If you prefer something different, no problem, suggest it. I'll edit this, and use whatever seems to have a consensus. Yes, A is short, but so what, it's frequently needed, clear in context, without a conflict (and saves typing!). The only ones that are brand new are A and TS.
