I am doing just about the same thing you are, and feeling overwhelmed also. The only difference might be that in addition to a running paper log (in a notebook with handwritten notes on each new promising match), I created a microsoft word table (I like it better than excel tables) that I can insert a new row when I find a positive match on the same line, ancestor, and make notes on which sibling the match is thru etc. That way I can quickly see that I have six matches to X common ancestor and who from...also make notes on this table about what kind of information is in the other tree and whether it is worth going back to look for more paper documentation etc. Not a great system. We definitely need more filtering tools as suggested, i.e. surnames at least. (On my table, I have five columns - username of match, family line it is in (i.e. maternal or paternal), name of match, notes on match, contact information if I followed up with message to match or not.
