A big family event, sure.
But I don’t think that people are that close to people merely because of their geographic proximity in the same parish.
Its not like back in the old country, people lived in a village and that’s all they saw. Or even near the start of the 20th Century in urban America, where most people didn’t have cars and stayed closer to home.
It isn’t like I don’t care about my neighbors, its just that I don’t know that much about most of them, they are out doing their own things.
Because of mobility, and modern telecommunications, people are less likely to be involved in such matters just because they are in the same parish. There is a good chance that more that 90% of the mother’s parishioners didn’t even know that she was pregnant with child.
