I have a little over 64,000 people in my data base, with approximately 5,500 different surnames.
All of this is in one FTM 2012 data base that has only one so-called “Island”
Even though you say you have five families you more than likely already have many more than five different surnames.
I don’t know how you can keep your genealogy straight/managed with five separate data bases. I would imagine that every time you encounter a new surname you have to look through five separate data bases to ensure that you don’t already have that “new” person in one of your five data bases. [And if you don’t look then you run the risk of having the same person in two or more of your data bases]
The larger your five data bases become the more apt you will have cousins marrying cousins. You probably already have that. If and when you do run into this what [do you presently do] or what are you going to do? [If two of your data bases are involved you probably put each “spouse” in both of the data bases]
My suggestion runs along the lines of that posited by Marco Scavo. I think you will be better able to manage your genealogy in both the long and short term if the five data bases were merged.
Yes I is true, that size and complexity slows down FTM 2012, and yes I complain that the system is slow, but I can’t imagine breaking up my one data base into X number of data bases just to increase the speed [it is so integrated with hundreds of cousins marrying hundreds of cousins over a period of a few hundred years, I wouldn’t even know how to begin to break it apart]
PS If you have it all in one data base you are more apt to find relationships among and between people than you would if you kept it in five data bases
