I am a descendent of Christian Erb, born in 1734 in Lancaster Co., PA, Father was Nicholas Claus Erb, Mother was Catherine, last name unknown. Over the past year I have been working in the GEDCOM file in the "ERB/LARKINS GENEALOGY" database. John Larkins is a relativewho split off in the mid to late 1800s. He has done a tremendous amount of work in my family.
Nicholas came from Switzerland in 1737 with his family and settled in Lancaster, PA. Later some of his family moved to Ontario Canada.
If this is your family too, I suggest you visit John Larkins website and brouse around.
