Essentially to find ancestors you need to be creative and you need to know the strengths and weaknesses of the kind of person you are researching and how that plays with search engines. The best people to research about are people who, in some way are famous, or infamous! Also ancestors you know some details about, and here we come to a key point - what you will hopefully unearth are unique keywords.
Let me look at unique keywords a bit more closely. For instance one of my ancestors has a middle name "corderoy". This is great for research via Google and in context of the full name gets some good hits and some useful web pages and documents. This person also lived in a house which at the time was called "chetnole", and that again helped find some useful web pages. These keywords are ideal to help your web research. Use them to find images, or search the web in general or in special search engines.
Also try to understand about how deep web research works. What I mean by this is that Google, and other search engines do not index all web pages. Also the ones they do index do not index them in ways that may seem logical. For instance I recently searched for one phrase without quotation marks and lo and behold Google correctly highlighted and found one page with that exact phrase. However after putting that same phrase in quotation marks Google reported, totally incorrectly that no pages existed.
Sometimes Google works better as a search engine that the specialist search engine actually provided by a particular website, and sometimes the opposite is true. You need to work with both to drill down deeply. So Google is good for giving you a clue that there may be some answers on a website. Then drill down into the website for more info. Once inside remember to retry Google with the kind of keywords that work for that website.
Now let me finally turn to searching for people's names you need to try different forms. Suppose someone's name is Alpha Beta Gamma then try searching the following forms:
- AB Gamma
- Gamma, AB
- Alpha B Gamma
- Beta Gamma
- Mr Gamma
- Mrs Gamma
- Mrs AB Gamma (remember that married women often were referred to by their partner's first names!)
- Mr AB Gamma
There may be other forms as well. These should be mixed with words such as home, death, born, married, family, mother, father and so forth. Also when you know dates try adding these to the search, especially years.
