Seanmháthair is 'grandmother' in Irish;the word is seanmhair in Scottish Gaelic, which is closer to 'seanvoir'.
Bairns is the Scottish word for small children - nothing to do with grandmother.
Seanmhair - almost like "shen-he-vuhr" if that makes sense, you will be able to listen to it on one of the BBC's Gaelic sites "Beag air Bheag" or "Colin and Cumberland" < two different sites.

The word is: 'tidsear', and it's pronounced 'teetsher'.
That is not a Scottish Gaelic word. It may be a word in the English dialect of Scotland ("Scots" or "Lallans"). Gaelic has no 'w' or 'y'.
