Starting Sept. 5, 2014, Genealogy.com will be making a big change. GenForum
message boards, Family Tree Maker homepages, and the most popular articles
will be preserved in a read-only format, while several other features will
no longer be available, including member subscriptions and the Shop.
I have a Minnetta Rogan in my family tree. I don't have a birth date for her, in fact, I only know her name. But based on her husband's age, she could be part of the family that you describe. Her husband was Francis J. Tiedeken b. about 1852 in Philadelphia, PA. They resided in Philadelphia at 319 Wildey (Ave, St., Rd.). He was a blacksmith.
I have lots of info on her in-laws, children, and grandchildren! Don't try to research the husband on your own. There are six "Francis Joseph Tiedekens" in Philadelphia that I know of. Fathers, sons, cousins, second-cousins...it can be very confusing.
