MIAMI (AP) - Generations of a Republican dynasty are in Miami this weekend to celebrate the wedding of former Florida Gov. Jeb Bush's youngest son.

Presidents George Herbert Walker Bush and George W. Bush and their wives were among the guests at St. Jude Melkite Catholic Church as 26-year-old John Ellis Bush Jr. married Sandra Algudady on Saturday afternoon.

The elder Bush appeared frail as he walked into the church with a cane wearing a white summer suit.

His granddaughters, Jenna and Barbara, were also in attendance.

Secret Service and police swarmed the family, who dined at The Rusty Pelican for the rehearsal dinner on Friday night.

The former governor did not respond to an e-mail seeking comment from The Associated Press.
