Re: just bought a brick row home!
I think the decision should be made on the style of the home as to whether divided lights are appropriate or not. Divided lights look great in the right environment but are a pain in the you-know-what to clean an maintain. To me, the grids between the glass do not give the appearance of divided lights, they look like grids between the glass and I wouldn't have them. That is just my opinion and I wouldn't want to force my opinion or taste on you.
