Well my maternal grandmother was adopted and never knew her natural parents. It is only in recent years when doing ancestry research that I found her blood ancestry, from which I found that I have Wallace, MacNair and MacLeod blood lineage. I also found a history of death by tuberculosis through the Wallace line, which was very interesting as my own mother died from TB as recently as 1992 which puzzled the doctors as it is a rare disease nowadays. I also found that gran's mother died from TB when she was a few months old, she was given for adoption by her father who re-married. She had always been thought to be an only child but I discovered she had two sisters who died in infancy from TB and a brother who died from TB before he was 30, but lived just long enough to marry and to father a son who would have been a full cousin to my mother. The son went on to become a coal miner and he married and had family with whom I have recently made contact for the first time. I also made contact with relatives of the family who adopted my grandmother who gave me some copies of magnificent old family photos.
