Hi sky and peter
I don't think i am necessarily suggesting that sky uses a professional researcher, especially for establishing his genealogical lines, this can be done over a period of time using the Internet and as long as you are able to confirm each generation to be accurate in at least 2 sources, then that is fine. It is the family history that may require a greater knowledge and familiarity with the vast array of sources. I am a strong believer in hands on meticulous research in the Local Study Centres (attached to main Libraries) and County Record Offices. The primary and secondary sources in these places are invaluable and can open up areas of research that can greatly add reality and interest to a genealogy and tansform it into a family history.
The only problem is that many amateur researchers may feel out of their depth delving into these unfamiliar sources, as i did myself at one time. There are however useful publications sold by Family History Societies and Family Tree Periodicals, that explain in clear terms where to locate the records, in what situation you would need to use them, how they were collected and compiled and in what form they are now available. The only commodity really required to access these records is ultimately 'time', and that is the one aspect of the research people find most difficult.
