Hi, you asked about information on Emma Brady's parents. You said her father's name is Alexander and her mother's is Elizabeth Todd.
The 1900 census says Emma Brady was born about 1872 in Missouri. Find-a-Grave says she was born 21 May 1873 in New Boston, Linn County, Missouri. So you can write to the Linn County, Missouri courthouse to verify her lineage - or write to the Find-a-Grave contributor (if it's a family member).

Okay, let's see what we find.
I think Emma's mother Elizabeth Todd may be Susan Elizabeth Todd.
