[or-roots] Looking for McLane

[dgoodma02 at comcast.net]

My Grandmother was Corabelle McLane born in Oregon abt 1874.  I've tracked this back through Samuel Mark, b. abt 1832, to  Isaac by abt 1760/70 in KY, to Duncan b. bfr 1765 in Mass.
Now I'm stuck.  I'm sure they are Scotts or Scotts/Irish but can't find any info.
I even tried MAROOTS.  Any one have any ideas?
