I posted the Maryland link since the sightings started there in 1957, so I figured that's where the legend got it's origin.
QUOTE(wiki Goatman Maryland)
Reports of the Goatman began in 1957, with sightings occurring in Upper Marlboro and Forestville, Prince George's County, Maryland.[4] From there, sightings spread to other states; with reports of the Goatman being made as far south as Texas in the 1960s, Washington and California during the 1980s, and as far north as Ontario, Canada and Cannelton,Indiana during the 1990s.
In all honesty though, if you guys have him down in Texas now, you can keep him.

edit to say
I actually just noticed in your wiki link that the Goatman from Texas has a different description.
Maryland's version is a half goat half man looking thing and the Texas creature is part man part gorilla. More like a Bigfoot I guess one could argue.
I guess we're looking at too different legends.
The section I read in the Maryland wiki link that says the sightings spread out to other parts of the country is what made me think it was the same creature with the same description.
