Philippa Campsie

My Great-Grandfather, James Campsie (born c1847 in Scone, Scotland) married a Jane Peddie (also born c1847, probably in Perthshire), probably in the early 1870s.

Her mother was also a Jane Peddie (born c1818, probably in Perthshire), but I do not know her husband's name nor her maiden name.

I would appreciate any information that would allow me to identify these ancestors more accurately.
