Brandon Blackstock's daughter Savannah Blackstock is reflecting on her dad's death one month after his passing following a private battle with cancer. Savannah, 23, took to Instagram on Thursday, September 24, with a message about grief and support from loved ones. "So far, 2025 has been a year full of 'Trust in the Lord and lean not on your own understanding.' As we're ending Quarter 3 I've found myself looking back at all of the love and support my husband and I have had through the lows and heartbreak," she wrote.
