Adin Pierce and his wife, Estella Masten Pierce, called Stella by all who knew her. She had lived near Mt. Morris, entered Geneseo Normal School, but had to leave after a short time because her father died, she was the oldest child, and had to help run the farm.

Adin went to Rochester Business College and he and Stella were married about 1895.

They had two children, Eudora and Lucille.

Adin brought his family to New York in 1901 and soon afterwards he established what proved to be a very successful fire-proofing business.
