Aaron J. Fowler-Knowles, 18, of Hulmeville, a former football player and a senior at Neshaminy High School, died of complications from a brain aneurysm Saturday at Thomas Jefferson University Hospital.

Mr. Fowler-Knowles played football at Maple Point Middle School in Langhorne. In May 2003, before the fall football season, he was chosen to play on the Neshaminy High School team. That month though, his mother, Anna Leighton, said, he was diagnosed with a brain aneurysm.

Surgeons could not remove the aneurysm and instead performed a brain-artery bypass. He was able to return to school but could not participate in contact sports. Though he couldn't play, he attended every football practice and every game. Last summer he coached his nephew Michael's touch football team.

Mr. Fowler-Knowles was planning to take his driving test this week, had ordered a tuxedo for his prom, and would have graduated June 13.

He loved to cook and bake, his mother said, and hoped to attend culinary school and become a chef.

In addition to his mother and nephew, Mr. Fowler-Knowles is survived by his father, John Knowles; sisters Christina Leighton and Amanda Leighton; a brother, John Fowler; grandparents Barbara and John Leighton and Dolores Lyman; and two nieces.

The funeral will be at 11 a.m. today at Tomlinson Funeral Home, 2207 Bristol Pike, Bensalem. Friends may call from 9:30 a.m. Burial will be in St. Mark's Cemetery, Bristol.
