Marguerite Dennison, a member of the Osage Nation of Oklahoma, celebrated her 100th birthday on May 2.

Family, friends and tribal officials gathered on Tuesday to mark the occasion. The Osage Nation Mineral Council presented Dennison with a Pendleton blanket, flowers and a cake, and Everett Waller, the chairman of the council, offered her a prayer.

"I guess just trying to live a good life and always believing in God and counting my blessings everyday," Dennison told KOTV.

Dennison has a long history with the station. In 1950, she won KOTV's first Mother of the Year contest.

"When she gets home she get our brothers and sisters clothes ready for school the next morning when she gets up in the morning she fixes four lunches and helps fix breakfast; for these reasons we think our mother should be television mother," a note from her children, Charlene and Mary, to the station read.

In 2011, Dennison told the station about her "big family" -- four children, 16 grandchildren, 42 great-grandchildren and 42 great-great grandchildren at the time.
