I have found that genealogists, as a whole, are very kind, and helpful to one another. I supposed it's because we all know about a difficult search we've had ourselves. There have been other acts of kindness given to me, and I expect there will be more, and I try to pass these kindnesses along to keep the chain going.
But here's the one that means the most to me:
I was looking for a small town in Hungary that my grandfather had come from. My Dad gave me the name of the town (Nagy Dam), and another name (Veszprem) that might be connected. But my Dad grew up never speaking Hungarian, and was in his late 60's at the time and his memory of all things Hungarian was spotty at best.
I had done a lot of searching through microfilm at the Church of Latter Day Saints and had found the names of some relatives. Then, I found the GenWeb site for Hungary and posted a query, asking if anyone had heard of the two places. One man answered, he not only knew the town, he had lived there, and his brother still did. He wrote his brother, who went out looking for the relative, and found him. The first man had me write a letter, send it to him, he translated it, sent it to his brother, who took it to my 2nd cousin in Hungary. My cousin in Hungary did not believe the connection at first, but after help from the two brothers, he realized that we were, indeed, cousins. The man who lived in America even went to visit his brother, and went on to meet my cousin and his family. He took pictures and sent them to me and he wrote me about the meeting. And so, a long-distance correspondence sprang up. I would write a letter in English, send it to the man in America, who translated my letter, and sent it to his brother, who took it to my cousin. My cousin then answered, in Hungarian, sent the letter to my contact, who translated it into English, and sent the letter back to me.
This eventually led to my sister and me travelling to Hungary to meet our relatives. I eventually lost touch with the man here in the US, when he moved, but his kindness will never be forgotten.
