I can't believe that Lady Catherine would only have heard Mr. Collins preach a sermon twice in six-plus months! I realize that the Georgian and Victorian eras were *not* the same, but I know that later in the 19th century, it was considered de rigueur for the "squire's" family to attend church weekly, at least in part to set an example for the tenantry. Lady Catherine definitely seems to qualify as the local squire, and I think the church she would attend would be the one closest to home. Perhaps she was away during part of that time? But I don't think she would feel that Anne could do a lot of travelling.

Also, even if Lady C. is not as wonderfully hospitable as Mr. Collins says ;-), I do think she would invite him to dinner more than twice in six months!
