Laura Bush posted a tribute to her mother, Jenna Hawkins Welch, who passed away on Friday.
"This Mother’s Day, I’m remembering my mother, who passed away at the age of 99 on Friday morning," Laura wrote. "Jenna Hawkins Welch was a true daughter of West Texas who loved her family, books, and nature. My memories of reading with her and stargazing under the Midland sky are reminders of the passions that she nurtured in me. Our family is grateful for her long and wonderful life. We miss her dearly."
Jenna Bush Hager followed suit.
"Waking up thinking of my precious namesake, Jenna Welch who passed away Friday," the "Today" host wrote. "How lucky I was to be named after a woman who taught me how to slow down and appreciate every bird, and every plant in West Texas. She read us poetry and taught us about every constellation in the sky. Her kindness and graciousness were as expansive as the West Texas horizon. So happy she’s reunited with her great love, our Pa after almost 25-years apart. Thinking of my mama too who lost her little mama right before Mother’s Day."
