Yes, my origins are from Madaba and I am Roman Orthodox; We use to go to the St. George's Church in Madaba and as a child attended the "Latin School"
....No, I have not attended the Abdoun Church, although I have seen it, very beautiful.
If you have family from Madaba, then most likely we are somehow related...a small world.
Yes, Madaba has changed tremendously, my family and I are the Original people of Madaba so I have very fond childhood memories, but most are wiped away with the urbanization and ethnic mix. I think it is like that all over the world.
Are you in Jordan or the States?
