It is often difficult to find out what a particular type a tree is. I’ve found a very good website that just requires you to check a single leaf from a tree to find out exactly what it is and identify the tree!
Tree Identification Using Just a Leaf
Of course, books are the best tool to find out what a particular type of tree is. Have a look at the books below to make sure you make a positive identification.

Sorry if these options didn’t help you lindsay. But I think the forestry website is the best one on the internet and books are practically foolproof.
If you are still struggling you could look for a tree study course in your area.
