Young Aunts

You may remember that Dawn Cronin was only six years old when she became an aunt to Tammy (Babler) Pomplun in 1963. Tammy's mom Linda was the oldest child of Harry and Anna, Dawn was the youngest.
Now, Dawn's daughter Becka became an aunt at the age of six with the birth of Maddie Cronin in 2005. Maddie's dad Cole was the oldest, Becka was the youngest.
Bev Crans' daughter Katelyn first became an aunt at the age of eight when Tracy had Megan in 1994. Tracy was the oldest; Katelyn the youngest.

This all ties into the span of giving birth. Anna had children over thirteen years from 1944 to 1957. Bev had kids over a 21 year span from 1965 to 1986. Dawn had kids from a thirteen year span, from 1986 to 1999? Tammy also had kids over a 21 year span, in three separate decades -- one in 1980, (and 86 and 88) one in 1990 (and 93), and one in 2001.
