Gavin Families of Lafayette County 1860 & 1870

In my attempt to tie families back to my Hughes & Hastings I came across a baptism for one of the children of James & Sarah (Hastings) Hughes (with my comments on possible connections):

Immaculate Conception Catholic Church (ICCC), Lexington, Missouri Baptismal: Oct 23, 1864; Sponsors: Thomas Gavin [unknown relationship, possibly a cousin to Mom, Sarah?] and Bridget Hastings [Grandmother?/Mom's side]; Edward Hamill

So, that prompts me to go look at the sponsors, and other Gavin families. Are they just neighbors? Kin? or County/Township Countrymen? So here's what I've come up with:

1860 census, Clay twp, Laf, MO (Dennis Gavin Adj)
Thos Gavin, 34, stone mason, Ireland
Mary Gavin, 25, Ireland
Michael Gavin, 2, had ditto (error?, or just in?)

Note that Michael was born in Ireland. Based on all of the commonality of Irish names, this may be a stretch, but I found what looks like pretty close fit:

Mayo Ancestors - Official Genealogy records of County Mayo, Ireland

Which fits pretty closely with his death certificate:
MO Death Cert:

DoD: Aug 8, 1930 - KCMO
Fa: Thomas Gavin
Mo: Mary Kane

Another tie in to County Mayo may be concluded from the baptismal record of a daughter, Mary:

I didn't find Bridget in some of the early census, but this seems to fit in as the daughter, which is also interesting in that locating the area in Ireland that a person was born is a very rare find within death certificates:

Missouri D.C.
Mrs. Bridget Gaven Gossett
23rd St., Davis Twp, Higginsville, Lafayette, MO
Widowed: William Gossett deceased
dob: Feb 22nd 1856 - pob: Westport, Ireland (which is nearby the townships noted)
86 yrs, 3 mo, 5 days
dod: May 27, 1942
fa: William [sic?] Gaven/ Ireland
mo: Mary Cain / Ireland
informant: Mr. J. T. Summers, Higginsville, MO

So this may fit to her birth:
----

Father's Name        Thomas Gavin

Evidence also appears to support that Dennis Gavin was a brother (adjacent to Thomas in 1860 census, and there were only a few Irish families in Clay Township in that census):
----

Dennis Gavin, 34, Coal Digger, Ireland
Mary " , 24, f, Ireland
Mary " , 5, f, Ind
-----
1870 census Lex, Laf, MO
Garven, Denis, 45, m, laborere, Ireland
  "  , Mary, 32, f, Ireland
  "  , Mary 14, f, Missouri (Indiana in 1860 c!)
  "  , Thomas, 9, m, "

  "  , William, 4, m, " (DoD 1919/MO)

So the conclusion I come to is, even if not blood kin, they appear to be within just a few miles of where I believe my Hastings were in County Mayo so they had something in common. Now if I could only find some descendants that I could compare DNA.....
