The 'e' in Géminard has an accent over it, but I am not sure how to type that.

An acute accent (é) is more than likely used so I corrected it. Feel free to change it copy/pasting Feelew comment should this proper name is written otherwise.– jlliagreMar 31, 2017 at 15:51
The pronunciation of Géminard is regular, i.e. the way it is written creates no uncertainty for a native speaker.
The most common one in France would be /ʒeminaʁ/, something like "zhaymeenahr".
There are however a lot of possible variations depending on the speaker but they shouldn't not prevent cross-comprehension. For example é might be open /ɛ/ and even perhaps a diphthong, a might be an /ɑ/ and there are possible variants for r like /R/ or /χ/ or even not pronounced at all. The stable parts are min and the fact the ending d is never pronounced.
Géminard etymology is possibly from the Latin gemini (twin) which gave both jumeau and gémeau in French.
1In Quebec, A before R in the last syllable of a word is likely to be pronounced /ɑ/ (a few exceptions do exist, like guitare or sometimes marre, but even these are not universally pronounced /a/). I agree that France is to some extent a reference in the language, but if one happens to travel in Quebec, /ʒeminɑʁ/ would become the most likely pronounciation encountered. Mar 31, 2017 at 16:36
@Feelew You are right. Answer updated to take variations into account.– jlliagreMar 31, 2017 at 19:31
