You did not include any dates, or approximate dates in your query.And, I'm not sure how much you may already have on your family.There are two Leon Ippolitos with wife named Josephine on the 1930 census in Jefferson Co, TX.
On the 1930 census, all in the 3rd ward of Beaumont, Jefferson Co, TX, are families of Tony & Nancy, Leon & Josephine and Joe & Lina.From census records I would say Joe is son of Tony, and maybe Leon is a brother to Tony.Checking the TX Dth Idx all but Leon show up dying in Jefferson Co, TX.That index begins in 1964, so if Leon died earlier, he would not make the index list.
Combined info from TX Dth Idx and SSDI:
Ippolito, Josephine C., b 23 Dec 1894; d 13 Fe 1978 Jefferson Co, TX; last residence Houston, Harris Co, TX; SS card issued in TX.
This Josephine would fit in the following family from 1930 census Jeffeson Co, TX:
Ippolito, Leon, h, 41, b Italy, It, It, came to U.S. 1900 Na " Josephine, w, 34, b Italy, It, It, came in 1908 " Rosa, d, 15, b TX " Leon, Jr., 8, b TX
If the Jefferson Co, TX Ippolitos are your line, you might want to check out Jefferson Co, TX GenWeb site.Looks like they have a few volunteers who will do specific lookups.Plus, check the archived section for county.Using the search feature on the archived site, there are 24 records of birth, death and marriages for Ippolitos.Including birth in 1927 of daughter of Joe and Lena.Lena's maiden name is Pace and on earlier census Joe's sister, Lula, and her new husband are living with the family, he is a Pace, too.
Looks like the family was in LA before the arrived in TX.
