For having an unusual last name, our relatives used the same first names, so confusion is easy.The Peter Jackson Vasser that I have was born in Kentucky in 1829 and died in Andrew CountyMo. in 1883, having maried Metilda and then Eliza.His brother was Joshua Vasser who was born in Tennessee in 1824, married Nancy and died in Arkansas. Other siblings were Levi, Lucinda, Nathaniel, Samuel and Celia. Even if this is the right one, I don't have much on Matilda. All this is in a book by Lyndal Vessar.
