Hi MS,
doesn't matter how you spell the name it will sound the same when you say it. spelling use to be a creative art, only in the past 100 years did it get to be an exact art.
the SSDI does not have spouses or parents in it.
your best doc's for that would be the death and birth certificates
you can drop me a note at Jim @ Blankenshipweb.com and let me know what you find. if I can tie your line into the family I can save you a lot of work, because I have a lot of it well outlined. that way you'll know where to look for information that will tell you more about them.
JIM
