Two identical Pictish stones

In Strathspey, close to the town of Grantown-on-Spey, there are two identical Class I Pictish stones. They date to around the 5^th/6^th centuries. They are located on the north bank of the River Spey. One is located at Inverallan and the other is located further down the river at Finlarig. Finlarig is actually located slightly north of the River Spey. The original location of the stone was at Ballintomb farm at the confluence of the River Spey and River Dulnain. The symbols include the crescent moon and V rod above the rectangle and Z rod. I’m not aware of any other identical stones which are so close to each other. This suggests they could be boundary stones. They could be marking the land of a local chief. There is an old hillfort at Lower Craggan just down the river from Inverallan. However, very little is known about it. The rectangle and Z rod is a common symbol in the area. There are two examples at Craigellachie and another close to Elgin. See the maps below for more info.

What do the symbols represent? They could be two Pictish dynasties or nations. As such, it could represent an alliance between both dynasties. On coats of arms, you often have the symbols of two or more families. Or they could be the symbols of pagan gods. It may be significant that the crescent moon and V rod is positioned above the rectangle and Z rod. The crescent moon and V rod is mostly found in the north of Scotland, and the rectangle and Z rod is mostly found in Strathspey. The crescent moon and V rod is one of the most common Pictish symbols. If it was the symbol of a dynasty, it was clearly a powerful dynasty. This might explain why it’s positioned above the rectangle and Z rod.
