Searched for: HER 1950 AND 1940 CENSUSES, both bounded on Texas. 1950 = coll. 62308, 1940 = coll. 2442, the same query shape on each: ?name=Mary_Cooper&name_x=1_1&birth=1899&count=50&residence=_texas-usa_46&residence_x=1-0-0_1-0 -- EXACT given and surname, birth ranked around 1899, resident in Texas. 1950: 17 rows, ALL READ. 1940: 20 rows, ALL READ. Two tighter passes first: exact birth year 1899 statewide (birth_x=1-0-0) returned 15 rows, every one a fuzzy match on a middle initial M (Mary M, Maurie H, Eva M, Berta M...), i.e. no Mary Cooper of that exact year in Texas at all; and Harris Co. (residence=_harris-texas-usa_1311) with the exact year returned ZERO.
Result: NULL IN BOTH YEARS, and the null is about TEXAS and about the name COOPER. The 1950 seventeen run 1894-1904 and are every one a Wife, Head or Daughter in a household that does not fit her; the 1940 twenty are almost all wives. SHE WAS UNMARRIED -- 'Miss Mary Cooper of Houston' in her brother's 1955 obituary [J.401] -- so she kept the surname Cooper and SHOULD be findable under it. That she is not is the informative part. WHAT THIS NULL DOES NOT COVER, and what to try next: (a) she may have been living in a SIBLING'S household and indexed under a misreading -- search on her brother Carl Clay Cooper and her sisters Imogene (Cooper) Shaw, John Henry Cooper instead of on her; (b) she may have been outside Texas in April 1940 or April 1950, and only the 1910 [D.664], 1955 [J.401] and 1977 [F.325] fixes are actually hers; (c) an institution or boarding house entry. Her 1930 census was NOT searched in this pass.

Name, age, birthplace and county fit her, but no record yet joins her to Huff - a Texas marriage record Mary Cooper x Huff is what would settle it.
