I'm slightly worried that the answers throughout this thread have not stood back far enough and addressed the underlying questions. This latest part starts with Neil asking
can i ask another question, i'm not so much looking for anyone in particular, but wondered if you have a regime for sifting through large family groups?
To me that suggests Neil has amassed quite a lot of data but is struggling to make sense of it all.
The first answer has to be not to try to start somewhere in the middle, or at the older end and work towards the present, but the traditional "start with what you know" ie yourself. Then start working backwards. The tree then builds up as a logical structure. Once you have gone back to grandparents, you can if you wish then also start to follow back down their children, ie your aunts and uncles, and hence cousins.
Whichever way you go, there is for each person a set of data. It makes most sense to record it on a person by person basis. This can be a computer or on paper. There are 4 essential elements:
basic biographical data, supplemented by more detailed information as it becomes available
and 3 links which point to
their parents
their children, if any
their partner(s) if any
The basic data set for each person must have a unique label, the links then point to other people, ie other labels. If done on a dedicated computer programme, this is handled pretty much automatically and if done well makes it simple to step from person to person and follow baranches through the tree. It should also facilitate display or printing of specific charts. But it can be done on paper, or on a computer without a specific programme.
In the context of the question, the "what needs to be done next" then becomes a matter of identifying the end points, which are those people for whom you do not have a full set of links.
Above all its this logical following of a trail from person to person. Finding another family of a given name and trying to work out where they fit is best avoided at the start.
Apologies for a slightly lengthy and "philosophical" reply!
