In 2016, while Mary was in Grade 4, her mother passed away after a long illness. With no relationship with her father and no extended family in Nairobi, Mary and her brother relocated to Mbauini, a village near Kijabe, to live with their grandmother. Sadly, her grandmother did not have the financial means to keep Mary in school, and for a time she remained at home. Her brother, being older, returned to Nairobi in an effort to earn a living.
In 2017, Mary was admitted into the Little Lambs program and was immediately enrolled at Kiambogo Primary Schoolin Grade 4. Adjusting to school after time away was difficult, and she repeated Grade 4 in 2018 in order to catch up. She persevered and continued with her studies, sitting for her Kenya Certificate of Primary Education (KCPE) in 2022. She passed her exams and joined Mbauini Secondary School the following year.
