Jill: I do have the Curtis you mentioned in your message in my husband's family tree. I have posted Curtis lineage on the main page of my web site "GenLinks." Right now I am in transition with my platform company, but you may be able to access the page with the following urls: http://spaldinggenealogy.ipower.comhttp://spaldinggenealogy.ipower.com http://www.spaldinggenealogy.comhttp://www.spaldinggenealogy.com Scroll down to the CURTIS FAMILY data and link.
If you Google "Spalding Family History" you may get an interior page, then click "go to main page" at the end of the text. I apologize for the confusion.
Get back to me if you access the Curtis data for comment, or if you can't access the page.
