I have run into a situation where a child was 5 months old by the 18th April 1910 (census), so was born about November 1909.
The child grows up, marries, and has children, then dies.
The death certificate, dated 22 Sept 1944, gives his mother's last name as Palmer.
A delayed birth certificate — sworn affidavit 5 Feb 1945, 4-plus months AFTER he died, claiming date of birth 21 June 1909, is signed by someone whose name is near unreadable, but doesn't look anything like Georgia Palmer, or Kelley/Kelly. There is also a strong possibility the mother was in Chicago in 1945, not Arkansas where the affidavit was sworn. (She was in Chicago in 1935, and still there in 1940, and there in 1961, but was buried in Arkansas in 1966.)
His Find a Grave memorial uses the dates per the death certificate — and the later delayed birth certificate.
A delayed birth certificate for his half-sister, sworn in 1961 and signed by a different hand as mother, gives mother's last name as Parrott, and is signed by Georgia Parrott McLain (which ties in with marriage documents from 1897).
I am 99.9999% certain this is the same man as the 5-month old baby from 1910's census.
How do I resolve the issue of the mother's last name not matching any other documents thus far found? (I have spent hours and hours looking for, and reading, documents for this family, particularly the mother.)
These two documents — death cert, and delayed birth cert — are the only places I have seen the last name of Palmer for the mother. Her stated place of birth matches what is known (not that that actually means a lot, because it could be anywhere within the same state). The state is Arkansas, and pretty much the family stayed in Jackson County.
The father's name and place of birth match everything else that is known (not a terrible lot).
Is it probable for someone to pretend to be someone else and make a sworn statement, thus breaking the law, just to have a birth certificate issued after someone was dead?
What would be the reason for getting a birth certificate for a dead person?
