husband still looking for birth family

We are trying to find anyone that may have any information about my husband's family. He was adopted in Quebec City Canada. Both families were very large farm families. His mother was around 17 years old and his birth father was 21. My husband, Frank was given a name by the Nuns at the Catholic Church where he lived for a little over a year after his birth. They named him Joseph Laurent Prinze. There has to be some family left there somewhere. At the time of his birth, there were about 10 children in one family, and 13 in the other. My husband has been very ill, and we have been trying to find out if there were any health issues in his birth family. He would like to meet some of them if they would like to meet him and his wife and sons. The sons are now 22, and 27. Both very fine young men. If anyone out there has any information please contact me ASAP. Frank was born on October 31,1954 ,and was adopted out of Catholic Charaties. He understood only French at the time. If anyone can help us it would be greatly apprecieated. He is 5'7" inches tall, Wt. 189, curly drk brown hair. Drk brown eyes, with long lashes. Very intelligent, and muscially inclined. Owns his own business in construction. Please contact us if you know anything.....anything at all! Thanks so much; Dana Payne Kole - Wife
