Kenneth Irvine Smith & Nina Ruth McLeod of Penobsquis, N.B.

I am interested in getting correct family information of my parents Kenneth I. and N. Ruth Smith and their children, grandchildren, etc. I started this in 1969, but have never really completed it or double checked the info. I am still slugging away. I have some siblings interested now, so maybe we will complete this as a team. We have found info for my mother's father back to William McLeod I, born before 1749.
I want to do the same for my husband's family. His mother's name is Verna Leggett and father's name Merton Boyd.
I am new at this, so any advice will be appreciated. I will be happy to share my information with relatives.
