Mary Rankin and her brother Walter.

Garrard Morgan's sister Mary "Polly" Morgan was married on September 26, 1834 to Robert Marshall Hamilton in Greensburg, Indiana. They were married in the home they would live their lives out together in. Their daughter Sarah Morgan Hamilton married John T. Rankin and they had one daughter Mary. 

Six years ago I asked the question, what happened to Mary Morgan Hamilton's granddaughter (Mary Rankin) who appeared to be named Mary for her grandmother?  

According to the Social Security Index Mary lived from May 16, 1884 until October 1973, and died at the age of 89.

Mary was her mother Sarah’s only living child in the 1900 census. Sarah claimed she had four children and sixteen-year-old Mary was then her only living child. Census numbers evidence such sadness.  

May 6, 1890

Walter, son of John T. and Sarah Rankin, died Tuesday, May 6, 1890, in the 9^th year of his age, of diphtheria, and was buried at Kingston Wednesday morning. He was a promising boy, and his parents feel deeply their loss. It seemed specially sad that, the disease being contagious, so few of their many friends could attend the funeral. Their beautiful home at McCoy seemed darkened by the angel of death. But the parents have the Christian hope of meeting the loved one in the beautiful world. He will be missed by his Sabbath school teacher and from his place in the church at Kingston, of which he was a baptized member. Services at the house and grave were conducted by his uncle, Rev. A. T. Rankin, and the body put to rest in his grandfather’s, R. M. Hamilton, beautiful lot in the cemetery. His sister, younger than he, has recovered from the same. It is hoped there may be no other cases.   From The Saturday Review.
