Thanks for the response. Irene is my great great grandmother. Willis and Irene's daughter Catherine "Kate" Blaylock is my great grandmother. She married Robert Gillmour.
I have a suspicion that Irene(a) Gibbs remarried after the death of Willis Blaylock. She was a Shaw when she married Willis Blaylock so she may be twice widowed. I do not know anything about her husband Shaw but we do know they had children because Mayor Louis Blaylock (as noted in his history) went into business with his half brother William Shaw.
I will continue to search for Irene but I am afraid I'm at a deadend. Maybe someone else on Ancestry will read this board. Thanks so much and let me know if you discover anything. Take care, Lisa Fox.
