It does not appear that George & Elizabeth had a son, Sylvester ("Sill/Syl").  Sill does not appear in the 1850 census with his alleged twin, William Henry, nor is his birthdate the same as William's, nor is it biologically possible for a woman to have children two or three months apart (Feb/Mar and May of 1850), nor does Sill appear in the 1860 or 1870 censuses with George & Elizabeth, nor does Sill or his wife or his children appear in either George's will or Elizabeth's will.  Also, my great-grandmother, Maude (THOMPSON) ROSE, daughter of our subjects' daughter, Delilah (McCRAY) THOMPSON, lived to be 98 years old and worked for years on the family genealogy, but never included a "Sill" amongst her aunts and uncles — and she would have known who her aunts and uncles were because Maude was orphaned as a toddler and was raised by her grandparents (our subjects), thus Maude knew her aunts and uncles well (she was especially fond of her Uncle Hen).  Surely, if she'd had an "Uncle Sill," she would have known about him, but she never included him in any family group sheet.

Looks like we've got a sloppy census-taker or a bad informant (the informant isn't necessarily the head-of-household, it could be a child or even a neighbor).  George should have been 48/49, Elizabeth should have been in her 40s, the "John," age 12, should be George, and the youngest two children were born in California.

Elizabeth lost an arm at age 16 in an accident involving farm machinery (a sugar press).  Because our subjects' daughter, Delilah Ann (McCRAY) THOMPSON, died giving birth to her third child, Elizabeth ended up raising Delilah's two daughters, at least until George W. THOMPSON remarried (in 1885).  Delilah's daughter, Maude Irene (THOMPSON) ROSE, remembered being raised by her "one-armed" grandmother.

6.  Abstract of the Will of George Clinton McCray.  Probate File #741, Solano Co., CA (extracted by Ruth Setterquist, Solano Co. Genealogical Soc.):

McCray, 56 yrs, of Maine Prairie son, Eli, 36, of Rio Vista son, David L., 35, of Fresno son, William, 33, of Maine Prairie son, Mark, 31, of Maine Prairie son, George, 20/25, of Maine Prairie son, Henderson, 19, of Maine Prairie (a minor) son, John, 15, of Maine Prairie (a minor) dau, Dora, 13, of Maine Prairie (a minor) dau, Mary, 22, of Fresno son, Wilson, 9, of Maine Prairie (a minor) gr. dau, Ada McGuire, 5, d/o Sarah, dec'd, of Fresno gr. dau, Caroline¹ D.

Delilah Ann "Annie" (McCray) Thompson's daughters were Maude and Louvernia.]

There is no town in California, that I know of, that begins with or is abbreviated, "SLA."   Could this be a phonetic misspelling of the acronym for San Luis Obispo (i.e., San Luis "Abispo")?  Maud and Louvernia's father, George Washington THOMPSON, was living in Indian Valley, which is near San Luis Obispo.

7.  Abstract of the Will of E.L. McCray.  Probate File #1597, Solano Co., CA (extracted by Ruth Setterquist, Solano Co. Genealogical Soc.):

That's Maud (THOMPSON) ROSE.  And, yes, it's Mary McGUIRE, not Mary McCARTY.
