Tracing Michael Madden (b.1804? in Galway - d. 1881 in Alabama-US)

Hello!

My name is Kimberly Madden, off due to COVID, so spending some rare free time tracking my heritage. This has led me to this board. What I have found so far through the Ancestry.com site is this:

My Great Grandfather was John J. Madden (b. 1890 Texas -d. 1936 Texas), He was married to Nancy Hashaw.

GG Grandfather, Delbert Madden (b. 1867 Texas -1928 Texas), He was married to Nancy Adeline Smith.

GGG Grandfather John Franklin Madden (b. 1829 Georgia - d. 1870 Texas), He was married to Margaret Jane Hutto.

GGGG Grandfather Michael Madden (b.1804 Galway -d.1881, Alabama). I'm using Ancestry.com and it shows Michael was married to Lenora Conahy (1805-1850). I believe I saw another member post that he was married to Mary Jane Carswell? Maybe he was married twice? I get lost on Ancestry.com!

Ancestry show a potential path from Michael to his father, potential GGGGG Grandfather, John Madden (b. 1780 Clontuskert, County Galway- d. 1865 Portumna, County Galway). John shows to be married to a Bridget Quinn (est b. 1784). 

John leads to a potential path to a possible GGGGGG Grandfather, Walter Madden, possibly John's father, Michael's grandfather, (est. b. 1763). 

That's as far as I have gotten without major chancing the 'hints' from Ancestry. I tried looking at the Lenora Conahy line and didn't get far. I haven't looked into the Margaret Jane Hutto mentioned in another member's post. 

Any tidbits or leads would be welcome!

Oh, I did the DNA from Ancestry and show this (my Mom was from South Korea, so this makes total sense in the distribution):

• Korea & Northern China 48%
  • South Korea
• England, Wales & Northwestern Europe 29%
• Ireland & Scotland 13%
• Norway 3%
• Germanic Europe 3%
• Japan 3%
  • Japan
• Basque 1%

Thanks so much!
