greats & ages

Yesterday, my daughter met her great-Grandma Robertson for the first time.  Today, I found out that Grandma had known her great-Grandma when she was little.  Her great-Grandma, Elizabeth Shickel Ritchie, was born in 1850.  ...imagine, one person connects my daughter to her great-great-great-great grandmother, and they were born 159 years apart (minus 5 days).
