The family of Jonathan Garber and Sarah Rife is profiled on p. 141 of The Garber Historical and Genealogical Record, Vol. III. The list includes 17 children, many of whom have no dates given, but those with dates of birth span the period of 1838-1860. This seems a very odd range of childbearing years for a mother born in January 1808, so I am not convinced that they are all properly attributed to this family. Their descendents are covered on pages 141-150, which includes an insert of pages 141-B through 141-H on the descendents of their son Daniel.
The date of birth which I have listed for Jonathan is calculated by subtracting an age at death of 76 yrs 2 months 28 days from his date of death, both probably from a cemetery inscription.
