Rogers Hornsby was a famous baseball player and is in it's Hall of
Fame. On Feb.29,1924, he married his 2nd wife, Mary Jeanette
Pennington. She died June 1,1956 in St. Louis,MO. I need her birth
details. She had previously married a man named John Hine, a salesman
of automobile supplies. She was older than Hornsby, who himself was
born Apr.27,1896.

Hi bluestreak-ga,

If there's an answer out there, it probably lies in one of two
directions:
1. By contacting Jeannette and Rogers Hornsby's son, who is apparently
still alive.

Wm Pennington Hornsby

2. By going to microfilm of the St. Louis Post-Dispatch

I've e-mailed several people who are doing genealogical research on
the Hornsby clan, but no one seems to know much about the second Mrs.
Hornsby. What I have turned up puts her in St. Louis for most of her
life. I don't have access to the St. Louis Post-Dispatch for the
relevant years, but perhaps other researchers do.

You probably want to consider raising the price of this question. To
get an answer is going to require a researcher to go to a library and
hunt through microfilm. I don't know if the St. Louis Post-Dispatch
was indexed back in the 1920s. As I'm sure you know yourself, this is
time-consuming and not pleasant :( researchers have to figure in the
time, effort and expense (if they need to travel somewhere).

Researchers: the 2nd Mrs. Hornsby's name is sometimes spelled
Jeannette, Jeanette or given as Mary Jeannette, Mary Jeanette. At the
time of her affair with Rogers Hornsby, she apparently went by
Jeannette Pennington and declined to mention her first spouse. Her
mother was good friends with the wife of a St. Louis gangster.

Hello luciaphile,                                                     
         You might be right. I've spent my last 7 yrs. sitting at a
library microfilm reader.  While I'm used to it, others aren't. The
other researchers probably haven't noticed, but I have raised the
prices on most of the questions I've reposted.  But not all of them.
I've also not posted many due to lack of interest.  If I didn't have
so many questions, I could pay more.  I need to be ready if a surge of
them are answered all at once. You do not know how much I appreciate
how much you've done.  You not only answered about 12 by yourself, but
you've commented on & helped others on about 20 others!!  If we can't
get a death date on Sarah Martin,  I'll credit you anyway for finding
her birth date, which is an accomplishment in itself.  Let's give
others a little while to see if her death date can be found.

Hi bluestreak,

Hope you're still checking this query.  The 1930 Census shows Roger
Hornsby and family living at St Ferdinand Twp, St Louis, Missouri:
HORNSBY Roger          33  (26) b. Texas    Head   Ball player,
National Leagues
HORNSBY Mary Jeanette  30  (23) b. Missouri Wife
HORNSBY William     4y10m       b. Missouri Son
PENNINGTON Theresa     52  (21) b. Missouri Mother-in-law
HENDERSON Esther       64  (19) b. Missouri Servant

The figure in brackets is described as "age at first marriage",
suggesting that both Roger and M-J had their first marriages c1923. 
Additional information suggests that Mary Jeanette's father was born
in England. The age given for M-J is at odds with the information that
you provided, suggesting that she was actually three years younger
than her husband.  However, I'm afraid I could not find any further
data in the 1920 or 1910 Censuses to continue the story.

Hope this is at least of some help to you.

Regards and best wishes,

Brett

Dear Brett,                                                           
         As luciaphile responded on Jan. 17, Mary Jeanette told the
1930 census enumerator that she was 30, but she was known to be older
than Rogers, and a liar.  But I am indeed still hoping someone will
look at my questions!  I still do not have Mary Jeanette's date of
birth.  She has been real tough.  I have seen this entry on the
census.  I have so many unanswered questions.  Feel free to pick one
out, and I promise to work sincerely with you, Brett.  bluestreak
