Hello, - 20 children!!!  I would first look in Guinness book of Records! All kidding aside, do you suppose it could have been she was in a foster type environment, and had 20 'siblings,' or even have provided care to 20 children? 20 children is a terrible amount for one woman to have. To have raised 20 children would require most likely , assistance from either a church or charity agency...I would start looking in that direction. As far the the Book, there are several sites that do searches for old or rare books, there is even a list that is for the trading, buying and selling of same. they will try to locate for you. There are websites for adoptions..Genealogy's MOST WANTED has an area for adoption, I believe Foster care would fit that category in many instances. As far as a book having your 'whole line'..I would tread gently there. It may well hold some keys, but it is unlikely that it is not without it's errors. Marcia Moore Collins
