When Stephanie Elizabeth Kanani Morrison married Scott Matthew Platt last month in Hawaii, she was more than happy to share the limelight with another woman — a maternal aunt, Frances Nora Wilsey, whom she cares for full time.

Both Ms. Morrison and Ms. Wilsey walked down the aisle at the Kualoa Ranch on the island of Oahu wearing white dresses. “She was not only my maid of honor but someone I also wanted to celebrate as if she were a bride herself,” Ms. Morrison said. “In addition to walking me down the aisle, I wanted her to have the chance to walk on her own.”

Ms. Wilsey suffers from Williams syndrome, which causes developmental delays and other health issues necessitating round-the-clock care.

On June 19, 2020, Ms. Morrison left her job as a public defender in Nashville to move home with her mother in Cape May, N.J., to help with Ms. Wilsey’s care. “I had reached a burnout point,” she said. “As much as I loved my clients, I asked myself, ‘Am I going to help these people or help my family?’ I realized no measure of success could be as important as spending time with Fran. She is so funny. She is just pure joy.”

To keep busy during the pandemic, Ms. Morrison started a 10-episode weekly podcast that July with Ms. Wilsey, called “Fran Says,” exploring various topics unfiltered. About a year later, when the world began opening up, Ms. Morrison and some college friends made a weekend trip to the Adirondack Mountains in upstate New York.
