Zachary John Denver is the adopted son of the late country singer John Denver and his first wife, Annie Martell. The couple married back in 1967 but struggled to have a child of their own, so they decided to adopt. A couple of years later, after Denver and Martell adopted Zachary, they gave another soul – Anna Kate – a home. And their father was definitely happy to have them, saying that they were meant to be his and Annie’s kids. In fact at the time, John Denver even said that he would be so happy to be remembered as Zachary and Anna Kate’s father when he passes away.
The siblings welcomed their half-sibling from Denver’s second marriage. Jesse Belle is the biological daughter of John Denver and Australian actress, Cassandra Delaney. And they were really close to each other as they grew up in the same house.
