Sure enough. Hebrew name was אַבְרָהָם = Abraham

Randy Schoenberg is the landesarchiv-bw site where that photo came from, or is it another source? (link not working for me)
Gilad's response was that he believes that means אַבְרָהָם should be his Hebrew first name, not middle name. Of course there could be practical matters at hand, too -- if he was known as אלברט איינשטיין once he became famous then we would want to continue to document that (perhaps in addition to אַבְרָהָם ?) I'll leave it to you to put it back as you see fit, but I don't think there's any value in putting "Abraham" in the English fields.
Albert Einstein As indicated previously, the name Abraham was not used by Albert Einstein in official/legal documents (including his marriage certificate to Elsa Einstein Lowenthal, Declaration of Intent, and US Naturalization document) although it may be his Jewish name.
Below is a permalink to the first of two images that contain Albert Einstein's birth record, showing Avraham as his Hebrew name and that (despite his family not being especially religiously observant) he was circumcised by a Mr. Strauss in Laupheim
