Hello,
Just recently the Massachusetts Death Index came online at
www.familysearch.org pilot search. Click on search, search pilot, click on US on the map, scroll down to Massachusetts. It is not completed, but I did find that one of James and Bridget's children died as an adult. His death is listed on this website including his mother's maiden name.
You can also search on
www.sec.state.ma.us for births, marriages and deaths in Massachusetts. These don't have records attached to them on line but if you join the Worcester MA
www.roots.com mailing group and ask for a look up have determining which record you would like to obtain, someone will usually look it up for you. I did see a possible marriage for James Grogan and Bridget in Worcester (her last name is not spelled the same way on both records).
These two sites are free to use.
If you need help finding the information, just ask, but I thought you might want to find it yourself.
