Rhisiart Hincks's Geriadur Kembraeg-Brezhoneg/ Geiriadur Cymraeg-Llydaweg was published in 1991 by Mouladuriou Hor Yezh, 1 plasenn Charles-Peguy BZH (=Bretagne/Brittany?) 29260 Lesneven. I bought my copy from Coop Breizh, 17 Straed Penhot, Roazhon/Rennes, 35036, phone 99-79-01-87 The people there are so wonderful that I beg you to buy it from them. I'm not sure about their language ability beyond Breton & French but they probably speak English. They also sell books in Welsh, as well as some Gaelic & Cornish materials, so maybe they know some. Rhisiart Hincks himself is listed as "Kelenner e Rann ar C'hembraeg, Skolaj Skol-Veur Kembre, Aberystwyth," i.e. Prifysgol Cymru, so maybe you could contact him there. I don't know if there is a Breton to Welsh half... if there is, please somebody let me know how to get a hold of it. --Antone
