ID numbers of Images and Names can be obtained by right-clicking the mouse over

the icon or highlighted name in a surname list.

 

If you don't want to spend a fortune all at once, but can't wait to get the 
data, you can find out who is related to whom for free by using the personal 
ID number which can be viewed by placing the mouse over the highlighted name 
and right clicking. People with consecutive ID nos probably live in the same 
house (to study the number in a more leisurely fashion you can import the 
data into a Programme such as Front Page and strip all the code to be left 
with just the name & number)
Here is an example from looking for "Smallman" & "Bridgenorth"

16128515 William Smallman 36 Shrops Brosley Salop Bridgnorth St Marys Dyer
16128516 Ellen Smallman 33 Shrops Bridgnorth Salop Bridgnorth St Marys 
16128517 George Smallman 12 Shrops Bridgnorth Salop Bridgnorth St Marys 
16128518 William Smallman 10 Shrops Bridgnorth Salop Bridgnorth St Marys 
16128519 Bertha Smallman 7 Shrops Bridgnorth Salop Bridgnorth St Marys 
16128520 Pollie Smallman 5 Shrops Bridgnorth Salop Bridgnorth St Marys 
16128521 Herbert Smallman 3 Shrops Bridgnorth Salop Bridgnorth St Marys 

It is not "good" family history to do this as the information is incomplete, 
William & Ellen above may be brother & sister and Herbert may be a visiting 
cousin. However it is a useful guide and a help to prioritise without 
spending all in one go.
