About Lawrence Sisson. I finally tracked him down )he had left Maine where he lived and painted Maine seascapes for many years) and yes he has his studio in New Mexico, either Albuquerque or Santa Fe and has had many exhibits. For our Gathering in '98 he sent me 10 of his lithographs and we auctioned them off. I haven't tried to find his lineage but I think he is of the Richard and Mary line. John
