BURCH, BIRCH, BURCHEF, BURCHETT, WHICH ONE.

Trying to find information on ELIZABETH BIRCH but not sure of the spelling.All I know at the moment is she married JACOB REYNOLDS and gave birth to my Great Grandmother MARIAH REYNOLDS.Records show her name as being spelled MARIA. MARIAHwas born 19 August 1861 in POPLAR CITY, MASON, ILLINOIS. She passed away 8 January 1935 in KEWANEE, HENRY, ILLINOIS.
Can anybody give me any information on this lady.What is the correct spelling of last name, who her parents were, where they were born.Anything will be appreciated even if it is to say sorry no information.
Thank you very much and have a nice day.
