Eva, It has been a long time since I have been in this forum.
William S. Terwilliger son of Cornellis Terwilliger was born Dec. 6, 1825.He was a twin.He married Phebe Curtis, daughter of Leonard and Zilpha Curtis.
They must have divorced as I found William died in 1876 in Oregon.Phebe .. must have remarried.The marriage lines were missing the last time I went to DeKalb Il to check for the information.You are more than welcome to contact me.I have had a small break from researching.It will be another full year before I am back to searching in full.
I am descended from William & Phebe, son Alfred & Mary Nichols,I have my line fairly under control minus Phebe death date and re-marriage. Lorrie
