Found this information in the Baltimore City Directory 1871-1873
Sarah is in the 1871 Directory which probably was canvases in 1870 to be published early in 1871, Robert is her brother. She is not in the 1872 Directory but her brother and her mother Margaret is. In the 1873 Directory none of the family is reported. There are about 10 Family Tress on Ancestry in which Sarah is mentioned 5 are Public. The only info on her in all 5 Public Trees is her birth year. Her parents are mentioned in the Public Trees Robert Close and Margaret Stuart Close. They are buried along with two of their children Ella and Robert John in New Cathedral Cemetery Baltimore City, Maryland Sec K Lot 80 N. A link to the Cemetery https://www.newcathedralcemetery.org/
I think it may be possible that Sarah may be there also.
