I am looking for a village in France. I believe it is called Saint
Ilere but I am not sure of the spelling. I  believe it is in northern
France but am not certain.
Please could confirm the correct spelling of the village name. Please also
advise where it is located.

Dear Memory, 

There are several villages that come to mind: 

In northern France, you can find Saint Hilaire les Places
<http://www.visitorama.com/87/Saint-Hilaire-Les-Places.html> 

And also : 
St Hilaire du Harcouet 
<http://www.ville-st-hilaire-du-harcouet.fr/specific/formats/index.jsp> 
In Normandy 

Saint Hilaire la Palud 
<http://www.st-hilaire-la-palud.fr/index.htm> 
Located in western France:

Saint Hilaire (Allier)

In central France

Saint-Hilaire-de-Riez

Western France 

I hope this answers your question, and did not add to your confusion.
If you need any further clarification on this answer, please contact
me before you rate it.

Perhaps this question is best answered by reference to a large French
road atlas.  My Michelin Atlas Routier France lists these.  Even this
list may not be complete - who knows if every village has been
indexed?

I hope this helps.

The map numbers run from West to East and then North to South, so low
