UPDATED again: From ACNS:
Revd Wamukoya was not initially a candidate, but after seven rounds of elections yielding no results, fresh nominations were invited from the Elective Assembly. She subsequently received the required 2/3 majority in both houses of laity and clergy.
Also, Meshack Mabuza, IV Bishop of Swaziland, sends these sentiments:
Congratulations to Ellinah for having made history as the first woman bishop, not only in the Province of Southern Africa, but in the whole African continent. As her predecessor I thank God for having played a role in the making of that history.
UPDATED: It appears Swaziland is the first in the 12 Provinces of Africa to elect a woman. The Anglican Church of Southern Africa, which includes Angola, Mozambique, Namibia, Lesotho, St. Helena, and South Africa, voted to ordain women at the 1992 Synod, which met in Swaziland.
The Rev. Canon Petero A. N. Sabune, Africa Partnership officer for the Episcopal Church, writes:
What a glorious day of Joy and wonder for the people of Africa. I was at the Synod in Swaziland in 1992, when the vote was taken to ordain women. The Synod was chaired by The Most Reverend And Metropolitan, Archbishop Mphilo Desmond Tutu and there were tears of joy and thanksgiving. At the Synod last year, Thabo the current Primate lamented on how few dioceses have women priests.
This is the day the Lord has made let us Rejoice and be Glad ! Amen

Bishop Alan Scarfe of the Episcopal Diocese of Iowa writes:
I am pleased to share with you news of today’s election of The Rev. Ellinah Wamukoya within our companion Diocese of Swaziland. The Rev. Wamukoya is Chaplain at the University of Swaziland (where we served together during Holy Week during my sabbatical)… She also [recently completed a term] as CEO of the City Council in Manzini… We celebrate with Ellinah, her family and the people of Swaziland, as we hold them all in prayer.
