Mexican people have long been present in North Texas. However, the Mexican Revolution precipitated increased migration of Mexican nationals into North Fort Worth. In 1908, The City Mission Board appointed Lay Missionary Lillie G. Fox to serve the community centered around the Historic Stockyards on the Chisolm Trail.  By 1909, she had organized Sunday evening services.  The significant turning point came when the Southern Methodists sent Deaconess Eugenia Smith to be the first Director of  what became known as the Wesley House.  Under her strong leadership, Sunday School classes were formed.  They grew rapidly and La Primera Iglesia Metodista, or  the "Mexican Methodist Church," was born.  The congregation grew rapidly under several able leaders, the first indigenous pastor from their ranks being Juan los Santos. The old saloon on Commerce Street  was demolished and the timber used to build a sanctuary. It was officially chartered in 1923 in the Methodist Episcopal Church, South.  In the late forties, the old white frame building was razed.  About 1952, the church name was changed to Iglesia Metodista La Trinidad. The congregation moved into the beautiful brick chapel, inspired the by neo-gothic architecture of First Methodist Church.  Less than a decade later, for an unrecorded reason, the building was sold to the fledgling Panamerican Golf Association. The congregation relocated to the Northside Church of God on 1300 Gould Avenue. With barely enough proceeds in hand, they made a near even swap for the property and dilapidated chapel. The PGA reportedly sold the Commerce Street building to Joe T. Garcia's Restaurant for a handsome profit which helped launch the philanthropic Hispanic Debutante Society.  The old brick building is now a banquet hall, La Puertita, at Joe T. Garcia's Mexican Restaurant.  The chapel on 1300 Gould has recently undergone several improvements, including a steeple and playground.

A few of the original families survive as members today.  But the congregation gladly blends newcomers with the founders.  La Trinidad United Methodist Church operates under the authority of the Rio Grande Conference of The United Methodist Church.

Minnie Eugenia Smith was born August 29, 1874, the third of eight children, and grew up in Union, South Carolina. Her parents were George Wilbur and Rosanna Martha Carpenter Smith.

Eugenia Smith wanted to be a missionary and managed to save $200.00 by working in a textile factory.  In 1904, at the age of 30, she was ordained as a deaconess and the same year obtained a scholarship to Scarritt Bible and Training School in Kansas City, Missouri.  After two years of training, she returned to South Carolina to become a pastor's assistant at Central Methodist Church in Spartanburg, South Carolina and served the people of Spartan Mills Village.  After two years of service in Thurber, Texas,  the Methodist Church appointed her to serve in Fort Worth - primarily to families of men employed in the packing houses and the Mexican immigrants.  Miss Smith started a Sunday School with two children that resulted in the establishment of La Trinidad United Methodist Church.  She was also founder of the Wesley House of Fort Worth in 1911 and its first full time Director.

Eugenia Smith was devoted to the less fortunate and had a passionate love for children, leading hundreds to Christ during her approximately 40 years of active mission work.  Due to declining health and what was described as "a very severe siege of sickness," Miss Smith retired in the fall of 1945, moved to Houston while recovering and helped a co-worker, Miss Elma Morgan.  She returned to the Arlington/Fort Worth area and continued enjoying the only hobby she ever had - loving and serving people.  Her testimony was quoted often: "I love my Lord, I love His Work, and I am still radiantly happy in His Service."  She died September 1, 1957 having devoted a lifetime to the Master's work.  She is buried in Shannon Rose Hill Cemetery in Fort Worth, Texas.
