What has this all got to do with time lines you may be asking yourself.
One of the ladies had a considerable amount of information about the ancestor she is researching but had gotten stuck regarding when he had come to the US from Britain. I looked at what she had and asked a number of questions e.g. have you looked in the census records, land records, military records, court records etc. Some areas she had a considerable amount of information, other areas were sketchy.
My suggestion was so create a timeline by looking at what she has and pulling out information from each piece of paper she owns. This would help her see what gaps there are in her research and what documentation she needs to pursue.
So where are you stuck in your research? Do you know what records to look for. In the above instance she needs to get a death record to hopefully verify parentage.
Just because you have looked at a piece of information once does not mean you have seen everything of relevance that is written there. Go back and take another look, I know I will be.
"And such". You never know where information can come from. In the previously mentioned researchers story she was standing in line one day and someone happened to overhear her talking. He had some information about her ancestor and gave her a copy. In another instance someone saw a picture she had and asked for a copy. It ended up in a book.
