MARSTERS/MASTERS, Stephen b1749 PA

Looking for info on this family.Known to have spelled both ways...Marsters and Masters.
Stephen Sr b1749, PA; d 1831 supposedly IN; m Susan Davis of Yorkshire Eng b1749,d1847 IN?
parents of:
Stephen Jr 1795 PA-1974 IN
m:*Malinda Baldwin Martin of IN b 1809
m: Elizabeth Guy 1799PA (1850 Census mar to Stephen and living in Marshall Co IN)
m: Nancy Crump b 9/11/1811VA - 7/14/1849
m: Hattie Rollins b 5/4/1832PA

Children of Stephen Jr:
a. Mercy Naomi Marsters 1817-1897
b. Susan Marsters 1819-1907
c. Elias Martin Marsters 1822-1849
d. *Malinda Martin Marsters 1824-1849
f. Stephen Spurlock Masters 1827-1892 (note last name spelling, per 1850 Marshall Co IN census)
g.Charles Bonner Marsters 1829-1908
h. Dr. Paul Davis Gannet Marsters 1831-1891
i. Saul Juden Vanglider Marsters 1831-1903
j. Jane Brown Marsters 1834-1849
k. Lusina Clark Marsters 1839-1929 (note 1850 Marshall Co IN census names "Levina, age 11", presuming her to be this child Lusina)

I am not sure which wives/mothers go with which kids.
I know that Stephen and Malinda Baldwin Martin had dtrMalinda Martin b1824-1849, mar Sylvester Nash Jr of NY; and she died in Marshall Co IN, leaving two little girls Louisa Jane b 1844 and Susan America ab1847.

It is my understanding that the majority of this family removed from Indiana to Oregon in late 1800's.

Any help out there with this family?

Info that I have comes from LDS, and has conflicts.
