hi,

If I have understood what you said, I think that the geoprocess you need 
is :

Analysis->Proximity->Spatial Join

In the picture you have an example of what I have understood about your 
situation, and how I solved it.

Insert  in the first position in the dioalog box the square layer. Then 
you will transfer the information of the parishes to its. You will need 
to consider what kind of mathematic process do you want to apply to the 
input data. For example, the population of three portions of parishes in 
the same square polygon will be summarized, and you will obtain also a 
field with the number of original polygons (parishes) intersecting the 
square. Check different options for get the best one.

I hope it would be useful.

Regards.

If I do it with union and dissolve I don't consider that some block maps are intersect by the border of a parish, e.g. the population will be the same even if only a part of the block map is within one parish.
