Rieta, I am trying to stay on track with how everyone is connected as I work through this, and my head is ready to explode, so I will only post briefly- I am working on families Laraby, Killenback (spelled many ways) Shaw, Monds, Slack.
Some of these families were from Lansdowne in Leeds County but the funny thing is they have a connection also to Barrie in Frontenac (or Addington, a boundary thing) County, and also to Plevna and Clarendon and to Kennebec.
I think that your Elizabeth Laraby could be a daughter of Seth Laraby and Hester Loyst who got married in Napanee in Lennox & Addington County, lived at Sheffield in L & A County, and moved to Kennebec. One of their sons died in Kent County, Ont.
I will post more about this, just let me get the rest of my research done here this morning. I might be able to shed some light on the Shaw family, Mary Killenbeck, children of George and William Killenbeck, etc.
How strange how this all happened that I got working on these families, was looking for one piece of info and you know how that goes...
