Sorry it took me so long to reply, real life gets in the way of genealogy sometimes - ha!
I can't find Sarah Bean, w/o William Smith in The KINGSTON NH EARLY FAMILIES, PATRIOTS, & SOLDIERS by Hosier, but that does not mean she's not in there. This book is laid out alphabetically and I only have photocopies of the various family lines that personally interest me. There are several Sarah Bean's listed as children of different men, but I don't know the father of your Sarah and I did not see any Sarah's in the parts I copied, that married a Wm. Smith. But I did not copy any Smith sections, so she could be there, under the Smiths, with William and their children.
I should purchase this book myself because I have so many different families in Kingston. Heritage Books is the publishing company, their address is 1540-E Pointer Ridge Place, Bowie, MD 20716, phone (301)390-7709.
