My great-great-great-grandmother, Margaret Ogilvie Downie, married Thomas Cuthbert; she was my mother's father's father's mother's mother, if you can grock that. Her brother, Anthony Downie, was born 31 Oct 1828 in Gorbals, Glasgow, Lanark, Scotland. He died 2 May 1877 at the age of 48 in Providence, Rhode Island.
Here is his death certificate. I had hoped to confirm the name of his mother. I know his father was David Downie. And the death certificate lists his name as David, so that's confirmed. This also confirms that his mother was named Jean. But I need some confirmation on her last name. Various records give it as McMicken or McMeaghan. But this only lists her name as Jean. I've also mailed California to get the death certificate for another brother, David Downie. Maybe that will show more.
