It would help if you indicated if that is an approximate birth date, or just a place of residence as there are 50 or more records for Carrie Werner's in MD in 1910- 1920 of varying ages. And whether or not this is a maiden named or you are looking for a married woman.
If you could include any names of parents, siblings, spouses, children and related dates of b, m, d it might be easier to narrow down the correct person.
Here is just one possibility although the birth year is 1915.
