Hi Barb,
Cheers for this - all's I can say for now is the best of luck to your friend - I'll certainly keep my fingers crossed. You might want to let him know what I've already tried to save him going over old ground. A lot of this was done back in late 2009 so I might have missed something out but this is as brief an overview as I can put together now.
The following have already been checked as possibilities for age, approximate period or transcribing errors:
13 Jan age 75 Manhattan #1652 - was definitely Jan and low certificate numbers come at the beginning of year
22 June age 70 Manhattan #18923 - wrong parents
30 June age 78 Brooklyn #13651 - wrong parents
The chap I used to correspond with on the Random Acts site before it stopped checked the alphabetical indexes at the NY Public Library and obviously these are the same as the Italian Gen Groups give or take any mis-transcriptions which we've obviously used. He did say that the death certificates at NYCMA are ordered chronologically, but only roughly, as they are received in the Health Department, from the ME's, coroners or MD's, so that there is a range of several weeks within any given section of the certs. He checked there too and I've tried the same approach using Steve Morse's system which allowed me to check EVERY certificate issued between 13 June and 16 June 1916 and if I remember correctly there seemed to be an absence of surnames beginning with the letter O for that period which I thought might be significant or merely a coincidence. Anyhow this link is useful for the chronological approach.

A lady at the NY State archives checked this out there and no joy and I thought I'd try NJ State as well with no luck either. Like I said earlier, given the 3 day period between death and a 9.30 am funeral I wasn't sure where to try next or how far out from NYC to go.
Convinced the error must lie at NYCMA - either mis-filed or lost and with no hope of making any headway there, I went back to Calvary given that in 2001 they supplied me with an interment list for the family plot of 2 graves - father, mother and 6 children. Since receiving this list I've applied for and received all of the death certificates bar one - Mary's! It's when I've cross-referenced the info from Calvary's list to the certificates that I've realised that Calvary's information MUST have come from the certificates themselves (whether this information is factually correct or not regarding age, etc) because it matches. So where did Calvary get the information for Mary - the certificate?
Mary A. O'Neil, June 16, 1916, age 81
Section 4, Range 15, Plot D, Grave 3
It was for this reason that I went back to Calvary - do they have any information extra to what they supplied - e.g. a certificate number attached to the burial details that I could go back to NYMCA with? They sent me back to NYMCA which is a sort of neat but pointless circle - haha. If Calvary don't have certificate numbers then so be it but I just wished they'd said that so I could close that route.
My only other thoughts on this now are why was there an absence of surnames beginning with the letter O for the period 13 June and 16 June 1916 when searching chronologically and would the fact that the probate process was complicated have any bearing? She died in the June but the probate wasn't completed until late October - surly that would be irrelevant as the certificate would have been needed for burial?
So Barb, you and your friend are my last hope and if there's no joy then I will certainly put this one down as I've tried but can't do any more. Good luck.
Sorry about the long reply but I'd hate for you to go over old ground.
