Baptismal record gives birth date of April 13. 1893 (Julian calendar). This converts to April 25, 1893 in Gregorian calendar. This conflicts with the birth date on the 1922 passport, May 12, 1893.
If the April 13 was misread as April 18, then April 18, 1893 (Julian calendar) would convert to April 30, 1893 (Gregorian calendar). This date could have been entered on some early documents, but later assumed to still be in Julian, therefore once again getting converted to Gregorian, resulting in a birth date of May 12, 1893.
