William McLean was the first person to own Lot 13, Block A, in the Town of Monrovia Subdivision.  The 1904 map issued Charles Slossen, a real estate dealer and property manager, shows the original configuration of the lot.  Like most of the other subdivided lots in 1886, the block was divided into lots that were 50 feet wide and 150 feet deep with an alley bisecting the block.  

In 1888, the property was valued by the tax assessor at $300.  The following year, it was worth only half that. From 1897 to 1903, the property was valued at $75.  After that, there was an uptick in property values with the price rising to $150.  That was the value on the property when McLean sold it to Alex Foster in 1914.

The 1907 Sanborn Map shows Lot 14 has yet to be subdivided though some houses are already appearing.
