I am researching the work of the art historian and critic, Walter Halsey Abell. I would like to contact any relatives for information on his family, his letters and the location of his private and art-relatedpapers.His parents were Edward Walter Abell and Bertha Maria Halsey. He was married to Marcella Marie Archard and they had 2 children, Marc and Alfreda. Walter Abell was a professor of art at Antioch College, Acadia University in Wolfville, Nova Scotia, Canada and Michigan State. He was the author of 2books on art and numerous articles in American and Canadian art magazines. Thank you for any help you can give me.
