The women met while growing up in their hometown of Yale, Iowa.

In 1947 they moved to Davenport, where Miss Boyack worked as a teacher and Miss Dubes worked for The Times and Democrat (a local newspaper) in the payroll office.
"We've had a good time," Miss Dubes said.
She continued saying the two have enjoyed their life together, over the years traveling to the 50 states in America, all the provinces of Canada - and even visiting England twice.
Miss Boyack said it took love and hard work to keep a relationship going for 72 years.
But friend Jerry Yeast, 73, who has known the women since he worked in their garden as a teenager, said: "I've known these two women all my life, and I can tell you, they're special".
Iowa first began allowing same-sex marriage in 2009.
