I learned yesterday something which subscribers may wish to check. Google has added what they call STREET VIEW to Google Earth. It lets a person go street by street where it is in place and view each side of the street. I looked up my great grandmother's house on E. 55th St., Cleveland,OH and it is still there and in good condition after more than 100 years. I was so surprised that it is so tiny considering they raised 13 children there. You may want to give it a try with your ancestors' addresses. It is in place in other cities also. djm
