Ummaya and Omaya are different spellings of Umayya, which is a non-Quranic name for boys and girls that means "servant", "slave", as in "servant of God". Umayya was a common name at the advent of Islam and many Sahaba and Sahabiaat (male and female companions of the Prophet, peace and blessings of Allah upon him and his companions) had this name. It is pronounced [(OO)ps] + [(MAY)] + [(YU)mmy] and can also be written as Umayyah, Omayyah, Umaia, Umaiah, Umayah in English. It is written as أُمَيَّة in Arabic.
