I am in the process of visiting the cemeteries in New York where Ladd's are buried and developing the information gathered into a website. The "Field Notes" area of the site is focused on the cemeteries with photographs, and transcriptions of the headstones. The "Biographical Notes" section includes: Articles, Biographies, Photo Galleries and other information on these family members.
The site is under construction, but I think that there is enough on line to bring you back later to check for updates. Check it out at: www.VintageViews.org/gravesite
My site is linked to my Uncle's site, where he has researched our branch of the Daniel Ladd line. His site has an online version of our tree, with over 10,000 individuals listed.
