The link you provide does not work, I tried it by just clicking on it and I copied and pasted it while signed in to my Ancestry (U.S.only) account, says I am "forbidden".
Clicked on other link and read some replies. For your information all Spanish American War Pension cards were included (by the NARA at time of microfilming) in the database Ancestry has as the "Civil War Pension Index:, Files 1864 to 1934" Notice the 1934 ending year...that is why Oscar Lindstom's SpAm Pension card image is there, as well as others. Ancestry has he filed in Montana, seeing Mont as but I feel it could is "Masst" for Massachusetts and has "E 22 Vo.S.Inf" and "C 16 Vo.S." Inf as units served. It noted his widow "Severino" filed in Sweden.
