The spelling of the name "Henshaw" can be a bit tricky because of its pronunciation. In IPA phonetic transcription, it is written as /ˈhɛnˌʃɔ/ where the first syllable is stressed, and the "e" and "a" are pronounced as "eh" and "ah," respectively. The "sh" sound is represented by "ʃ," which is similar to "ch" but with the tongue slightly further back. Finally, the last syllable is pronounced as "shaw" with a clear "o" sound. So, the correct spelling is "Henshaw," with emphasis on the first syllable.
