Clark Gibson and his first wife Margaret Coyle had three children. I’ve been able to find the Birth Record for only one of these children, namely Anna May Gibson.
Birth Record for Anna May Gibson
Click on the link for a PDF copy of the Birth Record for Anna May Gibson. The record shows that:
Anna May Gibson was born live on 04 Sep 1916 in the City of St. Albans, Vermont
She was white and the first child of her mother
The mother, Margaret Coyle, was 22 years old, was born in Ireland, and was living in Fairfield
The father, Clark Gibson, was a 22 year old farmer who was born in Fairfield, Vermont
The name of the informant was H. H. Johnson and the City Clerk was BM Hopkins
After the birth of her third child, Margaret Coyle Gibson returned to Ireland with the children, including Anna May. Clark remained in the United States. As far as anyone knows, Clark never heard from Margaret or her children again.
