Hello, looking for info on my Great Great Grand parents, David O'Brien and Mary O'Keefe. They were from Kildare Ireland and came to Michigan in the mid 1800s. They settled first in Flint, and then eventually out to other areas of Michigan & the USA. Their oldest daughter, Bridget, married John O'Brien and they settled in Alger County MI. The latest I can find David and Mary is in the 1870 Michigan census, living in Flint. I am wondering if they moved to the UP and lived with Bridget's family. Any info is greatly appreciated!
