Hi Dorthy, Do you think you descend from Asa Whitlock and ANN DAUGHDRILL? The numbers before Sarah Daughdrill's name , 1 2-1-1 1, are simply a numbering system used in this book to identify different individuals.
If the last digit is a 1 the person is the first child born in that generation.Sarah is the only child listed for this marriage.The book has the same date of birth for Ann Daughdrill as you have.
"DAUGHDRILL: A FAMILY HISTORY" byBobbie Jones Daughdrill is out of print.I found my copy over the internet.You can put in a search for used,rare and out-of print books, and then inquire at the booksellers that come up.I hope you find one. Rosette
