so, as we get further back in time, families were often quite large (though not all children lived to grow up). I'm wondering how to do a query to work out what ages, given known or calculated birth dates/years, all the people in a family would be on a particular date, of those who are known to be alive on that date.
For example, I've got a possible match in an 1821 census which gives ages by range (5-10, 10-15, for example), of 8 people. If I could get their ages at this date for all of them it'd make it easy to see if this is possible match.
Yes, I know I can work them out individually, but this problem's intrigued me to find if it could be done
Many thanks
