From MJ (mjoetta @ verizon.net):

In the 20 Jan 1905 Uniontown, PA "Tender Tributes" for Mrs,. Charlotte McNutt (Charlotte Layhue),
"Mrs. Louisa Morris, who is at the county home..." is listed as a surviving child. 
The 1880 Upper Tyrone, Fayette Co, PA census lists Humphrey Morris (age 31)and Louisa Morris (age
23). I think that Louisa listed in the 1880 Upper Tyrone, Fayette Co, PA census is Louisa McNutt,
daughter of Ruel and Charlotte McNutt.

Janet Mancini states that Albert Morris' birthdate is July 28, 1881 (from his obituary).

[It appears the census taker miswrote Humphrey's birthyear and age, since it should be 1847 and 52
years.  This record, along with census records in 1920 for Albert and Martin, establish that Albert
is the son of Humphrey Morris because Martin is listed later as his brother.  There is no indication
why Humphrey's wife Louisa, and his son Albert are not listed on this record.  Checking in later
census records for others in the neighborhood who were labeled 'Jeo', this appears to be an
abbreviateion for Joseph.]
