The first thing we usually ask is "tell me more". It is vital in order to avoid duplicate research AND assure we don't spend time giving you information you already know!
Every forum here is monitored by volunteers that have an interest in genealogy and want to help others.
Each board is unique in its focus.
If you have already posted to other boards, that information is not automatically available to the other boards.
The following suggestions are GENERAL, based on the information you provided on this board.
you can get clues even in difficult situations. Start with the known. When all else fails, review EACH bit of known information looking for something you may have missed.
1. William Bryant died in 1991
-- You ordered the death certificate (right?). It didn't help.
-- Review ALL documents surrounding the death to get a larger picture.
You said it contained what you already know. Did your family provide the information?
Still, REVIEW it to ensure you remember ALL that was written.
2. Louise Margaret (1930) or Margaret Louise was a child of William's that was:
-- Born in Pennsylvania.
-- Died in PA.
-- buried in Allegheny county, (Pittsburg area)
-- Do you know her birth date? It may be on her tombstone, listed in the FUNERAL home records, listed on her DEATH record.
-- The death month/year would be listed on the tombstone and on her Social Security Death Record, assuming she had an SS #.
3. Alma COX Murphy was William's wife and Margaret's mother.
-- You know Alma's birthplace and family information. Did that information provide any hints?
-- Did you find a marriage license for them in AL or PA?
-- What about her death record? Did she have an obituary?
-- She married at 16. Most 16 year olds did not travel to marry someone unknown by the family. Where did they meet and when? Did her family and his work together? Were the families connected through marriages? Find the connection and you MAY find more about your William.
4. Information from your Mom.
-- Do any other relatives know about your father?
-- Do they remember any of your father's relatives?
-- Did they/he mention any siblings, cousins, close friends?
No one exists in a vacuum. Their lives touch the lives of many people, one of which could have heard or known more about William.
5. William's statements about his family should be examined to determine possible facts. Then prove or disprove them.
a) When did they die?
-- Use this information to help narrow the possible parents.
-- Where was he in 1910?
-- Where were the possible parents in 1910?
-- Were they still there in 1920? 1930?
-- Look for death records.
-- Make a TIMELINE showing what information you have on William and his parents. This will help you see how each piece 'fits' with the other bits of information.
Information that is 'speculation' should be highlighted OR written in a different color to be proven later.
6. Do an informed search of the surname in the area of birth.
a) You may need to make a LIST of POSSIBLE candidates in AL and PA (to start).
-- Include those with a child in the age range as your William
-- Also consider nicknames or middle names (which could have been used in the census).
-- Look at their occupations (often, children took the occupation of their parents).
-- Look at family names. Any sound familiar?
-- Look at NEIGHBORs. Any surnames look familiar?
-- Follow them through 1930. Are they still there?
The good news is you have a list of possible birth places, which narrows the search.
A look at the Census records show several family group possibilities in 1920 for ALABAMA only.
Choctaw AL: b. about 1909
William (farm laborer)and wife Nora Bryant

There are more but I will stop here until I get a bit more information.
Brick walls are like a puzzle. Each puzzle piece, ALONE, tells you very little. You can only solve the puzzle when you Re-solve as many pieces as possible.
