I used the phone directory a couple years ago & wrote to probably 50 people from it, with little success. I am hoping that thru a message board post, I might find people who can fill in the gap between my last known relatives in Czech Republic (those born abt 1850 & earlier) & those that appear in the phone directory. I don't have info for possible relatives & descendants born between 1850 & the present. I have to admit that with my "mass mailing" I did find one relative (6th cousin) & may resort to that process again.
