|My brickwalls have been around long enough they are almost heritage listed.|
Having said that, I do re-visit them once or twice a year. Some times a fresh set of eyes works, sometimes there are newly available records. Most of the brickwalls still up are either from no records existing, or female ancestors who have appeared at their weddings out of thin air.
There is one goal I set every year, and usually fail. That is to collate the data I have found, and put it onto my tree.I often start, and then get sidetracked doublechecking a fact.
