Hi, From Monmouth Co. in 1920 that would probably Central R.R of NJ--defunct. If you have some fairly definite info you might try this---http://www.rrb.gov/ That's the railroad retirement board. Have you tried the 1900 census --she would probably have been listed with her parents. Not sure of town? Use the Soundex for Lista. You would have to go thru a lot of other names in that code if you don't know father's first name. Claire in Howell, NJ
