Hello All... The age difference was also who you talked to Mom or Dad...when the moms gave the info they were usually right on the money, but dads never remembered just how old the youngins were...hahaha.. My grandfather told me, when I was first asking him about his family, that he never could remember his brothers and sisters birthdays just who was older and could boss him...hahahaha... So even the family members could remember the birth order but not the ages...LINDA...
