Looking for Descendants of Kate Ann Christie MS Mckinnon Previous Marriage to J Ogston

Kate was born in Elgoll, Isle of Skye, Inverness, Scotland in 1890.

She married James McNabb Smith Ogston about 1913/14. Kate had a son, Donald and my mother Elizabeth Morrison Ogston (born 1915). James was killed 1916 at Mametz.

Kate married again in 1917. This was to Alexander Robb Christie.

I am unable to trace further information about Kate. It is possible Alexander married again in 1944 to a Margaret Reid. Kate may have died by then or they may have divorced.

I would be so pleased to hear if anyone has information about Kate after her marriage to Alexander.

Thankyou.
