I'm concentrating on those 27 names in red - http://bobgrahamclub.org.uk/index.php?page=missing I've a few leads now that I've cross-referenced members and pacers and with luck will get down to 20 or so from that sub-list. Some of those leads are a bit "six degrees of separation" but we'll see. Some of those listed weren't helped by existing members or helped others so are a bit of a mystery.
I think I can help you with a few on the "red" list Bob. Will email you.
