Don't get bogged down or hung up on "positive proof". Most clan associations don't require it. By definition, a "clan member" is anyone whose allegiance is accepted by the clan Chief, irrespective of any blood connection.
Many clan associations can be very helpful in sorting things out. Some have volunteer historians and/or genealogists with decades of experience, access to historical resources and a wealth of knowledge. Most also are eager to accept new warm bodies to help the association as their time and talents allow - helping to host clan tents at Highland Games, serving on committees, etc.. It can be a very positive and enriching experience which goes far beyond wearing a tartan and/or a cap badge.
