I am searching for a maiden name for Emma Vetter (wife of Ernest Herbert Vetter), both seem to have been born in Germany around 1835.

They were married in 1890, came to Maryland and had 2 children: Bertha M Vetter (born 1891) and Herbert Ferdinand Vetter (born 1893, died 1962). Both kids were born in Maryland.

Any info would be appreciated...I can't seem to find the name Emma Vetter in any other trees.
