Donald MacLennan, Kiltarlity, Inverness, Scotland

Hello I have found some christening registrations for a Donald MacLennan with the following children: Margaret 4 Sep 1736, Donald 27 Jan 1741, William 19 mar 1747 and Isobel 31 May 1752 in Kiltarlity, Inverness, Scotland.Does anyone know anything about this family, the mother and other children?I am hoping to find out if William came to Pictou, Nova Scotia abt 1773.I have found a William married in 1795 to Elizabeth Parker.I am hoping these are the parents of Margaret MacLennan born 1798 in New Brunswick.

Any help would be appreciated.
