Donald and Wainwood Mcdonald Tibbermore Perth

[Mollyrobz]

Please help me, I'm looking to find the parents of two people, the first is Wainwood Mcdonald and the second is Donald Mcdonald.
They married in 1776 Tibbermore Perth.
I think their children were as follows,
Margaret, David, Alexander, Ann and Helen Stewart Mcdonald. There may be more but I'm not sure.
I've been researching them for a while now I I can't seem to find anything. I think I may even of posted about them before but nothing came of it. I've found a few possibilities via familysearch but nothing definite

I see there was a Mcdonald born 1747 in nearby Logierait to an Alexander Mcdonald and a Janet Mcnaughlan. I wonder if there is a connection? One of Donald's and Winewoods children was named Alexander?
