My old kinsmen of Cato had some gaps and problems which I've fixed. The new and improved version sorts out the problems that came from attempting to link Cato the Elder to Cato Uticensis using Syme's family tree (my errors, not his). I've not seen a stemmata for the Porcii Catonis anywhere, so this just might be a UNRV exclusive. A real pain to construct, but also a joy for the discoveries to which it led me. I hope to do more in the future.
