Not sure if this what you are looking for: www.myheritage.com which allows the admin to give access to registered users to a given family tree. You should be cautious about this: both because of the strong chance that incorrect information might be entered – I know that Aunt Tilly was born in 1903 in Minsk and you know that she was born in 1905 in Pinsk and because you are putting information on the web that can be used and disseminated, whether the or not the information was correct, to other places on the web. I did some research and paid for some other research in an Eastern European country only to find that a distant cousin keyed it into a family tree program where another cousin copied it and put it into a public domain website. Most of it is accurate but when I have found inaccuracies or conflicting information I can’t correct it any more. A real sore spot with me, so I never give anyone any information any more except as a PDF or maybe in outline form containing only the direct ancestors of the person who asked for it. The last thing I am going to do is respond to someone, like a first cousin of my mother, who said, well just send me what you have. Years of research? Not a f****ng chance. So tread lightly, I have been at this for 13 years. Yet I must admit that a chance comment from my wife’s brother led me to a mailing list inquiry that someone answered me with a lead to a website that had digitized the newspapers from a small town in upstate NY which helped me learn the name of the father of my wife’s great grandfather that took me to another website that helped me find a book from 1903 on Google which was in the public domain and now I can trace my wife and my children back to the founder of Stonington CT and ultimately back to Boston in Lincolnshire England in the early 1500’s, so I have used the research of others also. It is a lot of fun but it still ticks me off when my research ends up on someone else’s website. SRM
