Adam Clay was born in Germany and came to the United States as a young child in 1853. He had a dry goods store at 1419 Washington on the south side of the street. That location would today be in the middle of Houston Avenue. The store remained in business as Adam Clay Estate long after his death in 1908 until about 1939 when Houston Avenue was redesigned and rebuilt.
In 1878 Adam Clay bought 2 lots on Colorado (then called Heiss Street) that had been part of a 20-acre tract bought by German immigrant Gregor Heiss in 1853. He built a house at 811 Colorado; until 1922 various people lived there as renters. In 1922 it was purchased by Adam Clay's daughter Agnes Clay and was occupied by her and her brother Adam Michael Clay until 1962. Something happened to that house. The current house was built in the mid 1940’s on Spring Branch Road in Spring Branch and moved to this location in 2010.
