I assume Elbert is still alive, you might ask him his father's name, too.If Elbert is deceased a copy of his death cerificate should show the names of his parents.If he is alive, a copy of his birth certificate should show both parents, plus where they were born, age at time of Elbert's birth etc.
Is Helen's middle name Mabis, or is that her maiden name?You need to know her maiden name, too.
We alwasys suggest to new researchers, talk to every family member who will respond, then be prepared sometimes not all info will match exactly, our memories can play tricks on us over the years.(^_^)
Also, some living people are a little touchy about their personal dates being put out on the internet. For example, the birth dates of Elbert's children.Names are OK, even where born, but birthdates a little sensitive these days.
When you get a little more on the names and where born for the family, come back, I have access to the 1930 census online.If Elbert was born in TX, there are 22 Blodgett families on the 1930 census and Elbert may belong to one of them.
