If you get a hit in the death index on a lady whose father's surname was, for instance, McHenry and whose married name was Whitmore, you can go to the birth index, leave the given name blank, plug in McHenry and Whitmore, and see if there are any children.
The Stanislaus clerk-recorder, at http://criis.com/stanislaus/official.htmhttp://criis.com/stanislaus/official.htm has some marriages. If the happy couple got married in a more romantic place, they won't show up here, but it is worth a try.
If the obit mentions a funeral home or cemetery, you can go to a nation-wide yellow pages web site at http://www.bigbook.com/http://www.bigbook.com/ and see if they are listed. If they are, and you write for information, you'll get better results of you include a stamped, self-addressed envelope and a $5 check. I usually say the check is for copying costs and ask them to donate the balance to the employee birthday cake fund.
Finally, I'm doing the lookups to repay some people who did me similar favors all over the country. They didn't need any help in Stanislaus County. They said I should do something nice for someone else. If you'd like to continue chain, go to the GenForum page for your county, pick a few queries that haven't been answered, and head to your local library. Unlike the chain letters, nothing bad will happen to you if you break the chain, and you won't get a financial windfall if you do, but you'll feel better.
