Helping a grandson who is desperately looking for the burial site for Bertha ROYLE PIERCE. She was born, probably in Council Bluffs, Pottawattamie, IA on 14 Feb 1879. I have all 12 of her siblings, parents and grandparents but she disappeared. Husband was Reuben William PIERCE, son Archibald PIERCE that I know of. Are any ROYLES still in IA anywhere? My husband's mother was a ROYLE so I need info on Bertha's family also. Thank you. Ann Cherry
