The map shown is from 1904 - 1909... the St Johns Catholic Church as we know it now was built long after the original structure at that same site when Charles & Ida were married. Indeed my wife's father as a child played in the church foundations as it was being erected in the 30's I think. To try and set the picture... from stories I have heard and research.... At the time they were married June 28, 1906, Monaca only had roughly 100 families as noted above. .... and actually the Church was on the outskirts of the town. Even Aunt Eunice born in 1921 says as a child she could name every kid in Monaca and their parents. 

Standing in front of the church at that time with your back to the front doors (facing East), in front of you was a huge valley which was part of the cut coming down from Monaca heights (now 14th street hill) .... you can see it in the above map as the green line. The valley extended all the way to the river and the Monaca football field is currently in the lowest end of that one time gorge before it entered the river. Indeed the Monaca swimming pool built the year I was born 1953, was eventually dismantled  ( I believe 50 years later) because it was shifting because it had been built on "fill" (in the gorge).
