L. Wesley Argo wrote two books on ARGO families. The name of the 2nd one is "The ARGO Families Revisited". You may be able to find some info in these at your library or thru an inter-library loan. The LDS in Salt Lake should have copies also. Wesley's address in 1987 was: L. Wesley Argo; 826 Meredith Drive; Media, Pa. 19063. In 1991 I was able to purchase the 2nd book from him. Hope this helps.
