Hello Kelly, Welcome to the world of genealogy.I'm assuming from the way you worded your query you are probably fairly new to this.Tossing out some surnames doesn't tell us much and I'm going to show you why. (^_^)
1920 census index for TX (I didn't even check numbers for 1930 census index):
Welborn - 59 in TX & 1 in Tarrant Co.(a female and black) Markham - 92 in TX & 3 in Tarrant Co. (white) Feemster - 19 in TX & 4 in Tarrant Co. (white)
So, let's back up a bit.Names, dates (or approximate dates) and locations are important to queries.Can you put some given names with your surnames?Maybe when and where they were born?By narrowing it down, I can see which on those indexes might be yours and come back with the information given on them.
