W.J. White Undertaker, Help Needed

Hello, I hope someone can help me.I have a copy of a death certificate for one of my ancestors from 1927 and the undertaker and embalmer is listed as W.J. White of Warren, Ohio.Does anyone know which funeral home Mr. White was associated with at this time?Do any records for this funeral home or Mr. White still exist and if so where are they?

The ancestor is Maud Helen Arn the daughter of Joseph William Arn and Dessie "Mary Ann" "Mollie" Debolt.She died June 29, 1927 at the age of 18 in the Jackson Township area of Mahoning County.

Any help or information very much appreciated.

In Christ,
Melissa Barker
