Henry Van Lynch, Sr, b 21 Nov 1898; d 4 Nov 1967 Kaufman Co, TX; last residence Terrell, Kaufman Co, TX; SS card issued in TX; single. [single can also mean widowed, separated or divorced]
Henry Van Lynch, Jr, b 16 Jan 1935; d 11 Jul 1976 Dallas Co, TX; no last residence shown; SS card issued in TX.
From TX birth index, mother listed for Henry Jr. is Helen Josephine Feltner.I do not find a match for Helen on death index.If she died prior to 1963, it would be too early for either of the above indexes.But, she might be buried next to Henry, SR.
You can obtain a copy of the death certificate for Henry Sr, and it should have the names of his parents.Accuracy only as good as the knowledge of the informant.But, he filled out his own application for a Soc Sec card, and it should have the names of his parents, too.
Look for an obituary for Henry Sr.You never know what helpful information will show up in an obit.Survivors are ususally listed, and sometimes a little bit about when and where they were from, or their family, if they were a long time resident in the area.
Once you have the name of Henry's father, you can look them up on the 1900 census, and begin to glean information on the family.Then from other records, you can start climbing up your family tree. (^_^)
If you think Henry Sr. was born in Kaufman Co, TX, I would check the Kaufman Co, TX GenWeb site.Some GenWeb counties are putting their cemeteries online, and some are getting other records, histories, obits etc online, too.Be sure to also check the archived section of the TXGenWeb Project for additonal county records. Happy Hunting.
