> The LDS originally microfilmed all pre-1916 sacramental records for the Archdiocese of Chicago. This includes all Roman Catholic parishes in Cook and Lake Counties. This was back in the late 1980s. A couple of years ago, they digitized the film for records prior to 1900 and scanned the actual records up to the end of 1925 for the closed parishes held by the Archdiocese of Chicago Archives. They were to do the open parishes as well but the second contract fell through.
In 1908, the Vatican issued a decree (Ne Temere) relating to the recording of marriages and of corresponding events in religious life. Proof of baptism, i.e. a copy of the entry in the baptism register had to be provided before the ceremonies can take place. After the marriage ceremony, or ordination to the priesthood, or of the taking of vows for the religious life had taken place, the details have to be sent back to the parish of baptism to be entered on the baptism entry. If you know where Margaret Anne was baptised, check the entry for her baptism. This 'should' provide the details of the religious community she entered and the date. Sadly, some such entries were never made.
If there are no details against her baptism entry, or if the register is not available on-line, then you should write to the Archdiocesan Archivist (you will find the details of this at http://archives.archchicago.org/
). You will need explain your interest, and there will probably be a fee. You could ask about houses of OSF nuns in the Chicago area, as there may be different OSF communities, some of which may have several houses. You could then write to the Sister Archivist of the communities with several houses to see if they recognize Sister Mary Martin de Porres.
Hope this helps
