You haven't posted before, so I hope you don't mind a bit of advice.You will get a much better response if you put more information into your queries, particularly locations and some idea of dates.
I'm going to take a stab at your query.I use www.familysearch.org for most of my on-line research.It is a free genealogical search site.
There is a death record for a Martin East, who died 25 August 1939 at Hackberry, , Cameron, Louisiana.The death record gives his wife's name as Mary Benoit, his parents as Thomas East and Mary Simon, his age as 56, and his birth place as Rayne, Louisiana.The death record is here: https://familysearch.org/pal:/MM9.1.1/F39R-5QM
Assuming that this is the Martin East that you are interested in, the next step is to look for the censuses.
A Martin East married to Marie was in the 1930 census of Cow Island, Cameron, Louisiana with the following family: Household Gender Age HeadMartin EastM 49 SpouseMarie EastF 49 ChildAmbrose EastM 21 ChildFelix EastM 19 ChildRemy EastM 16 ChildPierre EastM 15 ChildDorcilie EastM 11 ChildMathilde EastF 9 ChildDuplicie EastM 8 The 1930 census record is here: https://familysearch.org/pal:/MM9.1.1/XMYM-FQW
Does that sound like the family you are looking for?
Working backwards is the censuses, the 1900 census shows a Marten East in the household of Thomas and Margaret East at Wards 1-2, Cameron, Louisiana: Household Gender Age HeadThomas EastMborn May 1855 Louisiana, married 20 years SpouseMargarett EastFborn January 1863 Louisiana, mother of 8 children ChildDema EastMborn August 1881 Louisiana ChildMarten EastMborn Jun 1884 Louisiana ChildUsier EastFborn March 1887 Louisiana ChildNatalie EastFborn June 1888 Louisiana ChildDarlie EastFborn October 1890 Louisiana ChildRamon EastMborn June 1893 Louisiana ChildMargarett EastFborn April 1895 Louisiana ChildEuzied EastF born April 1898 Louisiana The 1900 census is here: https://familysearch.org/pal:/MM9.1.1/MSPY-5F9
You will find that both birthdates and the spelling of names were very fluid prior to the latter half of the 20th century.A lot of people were missed in the censuses, and a lot of births, marriages, and deaths were not recorded in public records (or have not been put on the internet).
Surprisingly, another way of gathering information on an ancestor is to Google them.This is the webiste of an Article on The History of Hackberry, Louisiana, that gives quite a bit of information on the Martin East family. http://ereserves.mcneese.edu/depts/archive/FTBooks/hackberry.htmhttp://ereserves.mcneese.edu/depts/archive/FTBooks/hackberry.htm
