Hi I am looking for this family...the name on 1850 census says SELLS, but I beleive it may be SILL.

MICHAEL SELLS .. .. .. ..1824..Pa.
ELIZABETH SELLS(SPEECE).. 1821..Pa.
DAVID F. SELLS .. .. .. 1848..Pa.
GEORGE H. SELLS.. .. .... 1849..Pa.

I would like to contact someone on here by the name of 'JenOliphant' who has this family in their tree.
How do I do this ?

George H. is possibly my great grandfather.
Thank you .. Jean. in Ozz
