My maternal grandparents were a huge part of my life: Flo (Florence) and Dolph (Adolph). Paternal grandparents died before I was born. When my son was born, we named him Andrew (the A for my grandfather, was NOT going to use Adolph! and my nephew beat us to Aron) Loren (for my father, who was called Lefty by everyone who knew him). Daughter Jennifer Wyle was named for two great-great-grandmothers named Jenny and Jane, and Wyle is my MIL's maiden name, and it is traditional in this family to give Wyle as middle name to the first-born.
Don't worry about Grandma Brittany. There will be a gazillion Grandma Brittanies by then, trust me!
