This is not a Birth Certificate but I note that Find A Grave via FamilySearch says:

Name: Emilie Clement Iznaga Maiden Name: Event Type: Burial Event Date: 1944 Event Place: Bronx, Bronx, New York, United States of America Photograph Included: Yes Birth Date: 30 Apr 1864 Death Date: 01 Nov 1944 Affiliate Record Identifier: 112422133 Cemetery: Woodlawn Cemetery

Citing this Record: "Find A Grave Index," index, FamilySearch (https://familysearch.org/pal:/MM9.1.1/QVG7-C7SS : accessed 20 March 2015), Emilie Clement Iznaga, 1944; Burial, Bronx, Bronx, New York, United States of America, Woodlawn Cemetery; citing record ID 112422133, Find a Grave, http://www.findagrave.com.

The birth date of 30 Apr 1864 is consistent with a number of immigration and passport records at FamilySearch which provide birth dates for Emilie Yznaga of:

• 1864 once
• 30 Apr 1864 twice
• 31 Oct 1864 four times
• 1865 once (spelled Emilia Yznaga)

It may or may not apply, but I suspect that relatives in their grief may struggle to remember a date when providing information for a death certificate at short notice, and have much more time to get it right when ordering a gravestone.

As commented by @bgwiehle:

1. The Find-a-Grave memorial apparently was edited since FamilySearch indexing - currently has birthdate as Apr. 30, 1860. Memorial has obit transcripts and photos, current owner has Inzaga in the username, so may have additional information if contacted.
2. Passport applications include references to supporting documentation; however, the few [@bgwiehle] looked at didn't include a birth certificate. Interesting that Emilie's always signed as Ynzaga, not Inzaga.
