Now, you'll have to do some research to prove the following, but using your grandfather's name, here we go.

TX Birth Idx, this is recorded twice with change in middle name:

Wishard, Franklin Cyrus, b 24 Oct 1937, Fannin Co, TX
Wishard, Franklin Gerald, b 24 Oct 1937, Fannin Co, TX
Father: Franklin Cyrus Wishard
Mother: Carra Margarite Shelton
[Does that sound like your grandmother's name???]

Often early records have misspellings, and from time to time people will use first name, then use middle name as a first name. And, location of birth for self and parents may vary, too. [sic] means I typed as shown, not a typo.

1930 census Fannin Co, TX:

Wisshard[sic], Frank, h, 30 md @19 yrs of age, b TX, MS, TX
" Carra, wf, 28, md @ 18 yrs of age, b TX, TX, TX
" Pauline, d, 8, b TX

1920 census Fannin Co, TX:

Wishard, Frank D., h, 20, md, b TX, IA, TX
" Carra, w, 18, md, b TN, TN AR

Same page - looks like Frank's parents:

Benjamin F., h, 51, md, b IA, IN, IN
" name not clear, w 45 md, b TX, MO, MO
" Clifton, s, 17, b TX
" Emmett, s, 15, b TX
" Florence, d, 12, b TX
" Lucile, d, 10, b TX

1910 census Fannin Co, TX

Wishard, Ben, h, 41, M(1) 19 yrs, b IA, OH, IN
" Nancy L., w, 36, (M1) 19 yrs, 9 ch, 8 lvg, b TX, MO, MO
" Edna E., d, 17, b TX
" Vina, d, 15, b TX
" Ethel, d, 13, b TX
" Frank, s, 10, b TX ** here's Frank
" Clifton, s, 7, b TX
" Emmett, s, 5, b TX
" Alma, d, 2, b TX
" Lucile, d, 5/12, b TX

1900 census Fannin Co, TX, pg 77:

Wishard, Ben, h, b Nov 1869, 30, md 10 yrs, b Ioway, Ioway, Ioway
" Lucinda, w, b Jul 1873, 26, md 10 yrs, 5 ch, 4 lvg, b TX, MO, MO
" Edna, d, b Jan 1893, 7, b TX
" Vina, d, b Jan 1895, 5, b TX
" Ethal[sic], d, b Jan 1897, 3, b TX
" Frank, s, b Jan 1900
[I doubt all of the above children were born in January. Enumerators had to do some math if a person's month of birth was after the official date of the census. Note Ben born NOv 1869, age 30, he wouldn't turn 31 until Nov of that year. I think the enumerator just made it easy on himself and chose January for all the children, no math. Note how spelled Iowa, too. LOL

Page 249, probably Ben's parents:

Wishard, Robert B., h, b Nov 1830, 69, M 47 yrs, b IN, KY, KY
" Lavina, w, b NOv 1831, 68, M 47 yrs, 9 ch, 7 lvg, b OH blank, blank
" Emma, d, b Dec 1861, 30, sgle, b IA

1880 census Fannin Co, TX. This is obviously the right family, but you need to look at the original handwritten record. Looks like this indexer was having trouble with the writing, it helps when you know what the names "should be." At least you know they were in Fannin Co, TX by 1880.

If you go to Rootsweb's WorldConnect site -- http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi -- Type in Wishard, Robert, born 1830 + or - five years. You'll find others working on this line, also. Looks like they take it back to Scotland. Just be careful, see if they have sources for their information. Some people just copy and post without verifying.

If I didn't make something clear, feel free to respond and asks questions, I'll try and help you.

Happy Hunting (^_^)
