The spelling of the name "Schroer" can be explained with IPA phonetic transcription. "Sch" is pronounced as "ʃ" which is a voiceless postalveolar fricative, "r" is pronounced as "ɹ" which is an alveolar approximant, and "o" is pronounced as "oʊ" where two symbols represent a diphthong - a combination of two vowel sounds, /o/ and /ʊ/. Finally, "e" is pronounced as "ə" which is a schwa sound - a neutral vowel sound. Therefore, the correct phonetic representation of the spelling of the word "Schroer" is /ʃɹoʊər/.
