I am trying to create a source citation for a St. Louis, Missouri Declaration of Intent for a "Leizer Poupko" from 1932, found on Ancestry.It is grouped with his Petition for Naturalization, filed in Boston, Massachusetts, in 1937. If you have access to Ancestry, it is the first result when search with his name. Typically, when I cite, I like to describe the underlying source, usually some NARA publication and microfilm roll. In this case, I am stumped as to the actual source Ancestry used. They cite some recordset that spans 1845 - 1911. But this is a 1932 record. They cite the NARA in Waltham, but reviewing their holdings, it does not seem they have it. Can anyone point me to a clearer source of the source?
