Daisy True Ryan is the adoptive daughter of American actress Meg Ryan. 

Meg adopted her daughter from China in 2006; she adopted Daisy as a single mother after her divorce from her former husband Dennis Quaid. Prior to adoption, Daisy shared son Jack Quaid with her former husband Dennis. The three, i.e., Meg, Jack, and Daisy, lived together in their Los Angeles home after the adoption was finalized. 

However, the information about Daisy's biological parents has not come to the surface yet. She might have been too young to know much about her parents, as she was just 14 months old during her adoption.
