How Are These Two DNA Shared Matches Related to Each Other?

My husband shares 20 cM across 2 segments with one of his DNA matches. I wanted to figure out their relationship because the surname Ungi from the match’s pedigree chart was familiar to me. I had seen it on family records originating in Gyoma, Hungary where my husband’s paternal grandparents were born.

I was also curious because this 20 cM-match was a shared match with someone else, a 143 cM-match that I found several years ago – without using DNA.

I started with the 20cM-match’s pedigree chart. There was a great-grandmother (Ungi Juliánna) who died 7 March 1950 in Hahót, Hungary and had been born 29 years earlier (about 1921) in Gyoma. Eventually, I was able to make this diagram showing the relationship between my husband’s two matches.

I didn’t make a separate chart, but my husband and his 143 cM match are 2nd cousins once removed.

Here are the supporting documents I used to make the chart. (You will need to be signed into a free FamilySearch account to see these records) Names on the chart are in bold:

Hahót, Zala civil registration death record line 12, Ungi Juliánna, died 7 March 1950, age 29, from drowning. Her husband was Domján István. Her parents were Ungi Zsigmond and Kéri Mária.

Gyoma Marriage Civil Registration, Page 102, Date 10 December 1898, Groom Ungi Zsigmond, born 16 August 1874, the son of the late Ungi Lajos and Kéri Juliánna. Bride Kéri Mária, born 25 March 1879, the daughter of Kéri István and Szalóki Zsuzsánna.

That’s all the documents I needed to show how they were related to each other, but how is my husband related? Here is a chart showing how he is related to the 20 cM match:
I found some other family records that may interest you:
Marriages and Children of Juhász Erszébet
23 October 1839 The Reformed Church marriage record states that Szűts György’s son Mihaly, age 37, a widower, weds Juhász Janos’s daughter Ersébet, age 21. He was born about 1802; she was born about 1818
02 Aug 1841 son Szűcs Mihály 

19 Oct 1852 son István Line 306, parent Rác Mihály’s widow, Juhász Erzsébet. Note in margin states that István got permission to change his surname from Juhász to Kéri, the surname of his stepfather Kéri Mihály
14 September 1853 marriage record to the widower Kéri Mihály states that she was the late R. Szűcs Mihály’s widow. It should be noted that Kéri Mihály’s wife of nearly 24 years died just a few weeks earlier on 10 August 1853 during childbirth. You can read more about Kéri Mihály in my posts, 550 Godparents and 543 Arithmetic and Genealogy.

Some of the information above I found a few years ago, but finding new tidbits of information about a cousin or ancestor is so exciting. I hope you can discover the thrill yourself!








543 Arithmetic and Genealogy

Doing genealogy is like working on a puzzle. Sometimes the smallest detail can be so important when determining who a person is. Sometimes doing a little adding or subtracting can be very helpful, too.

543-Subtracting dates


Unfortunately in the 1800’s many people were illiterate, and their arithmetic skills were sometimes lacking even more than that of people today. The ages given at marriage are not always accurate perhaps because the people didn’t know their true age or possibly because they added or subtracted a few years to appear older or younger than they really were. Sometimes the ages given at death are a little more accurate.

In the town of Gyoma in Békés County, Hungary there were several men named Kéri Mihály (Michael Keri). One of them was a widower who married a widow named Juhász Erzsébet (Elizabeth Juhasz or Elizabeth Shephard) on 14 September 1853 in the Hungarian Reformed Church in town. Their marriage record stated that he was 48 years old when they married, and the bride was 34.

I wanted to know exactly who this particular Michael Keri was. I looked through the Reformed Church records to find out more about him. I decided to look for his death record hoping that it would list his wife’s name on the record to help identify him.

I already knew that one year and six days after their wedding, the couple’s only child was born, a daughter that they named Lidia. Since her christening record indicated that her father was still living when she was baptized, I looked at death records beginning the very next day. After searching through over 15 years of records, I found two death records of men named Michael Keri. Unfortunately neither record mentioned a spouse or any other pertinent information. Were either of these men the person I sought?

I kept looking until I found his wife’s death record. Her record had much more information on it. It said that she was the wife of the late Keri Mihály so I knew for sure that one of those two men was her husband, but which one?

Since HER death record said how long she had been married and how long she had been widowed, I put that information at the bottom of the following chart next to her name, Juhász Erzsébet. I also did a little arithmetic to try to determine which Kéri Mihály best fit the numbers on her death record and put their numbers above hers. Thus this chart compares information from the death records of these two men named Kéri Mihály who lived in the same town and died about the same time with the information given on Juhász Erzsébet’s death record.

Comparing Death Information from Erzsébet and Two Men Named Mihály

I’ve highlighted in green that one of the men more closely fit the number of years of marriage while the other man more closely fit the number of years she would have been widowed.

I wasn’t any closer to determining which of these two men was her husband than I was before! But then….Look at the house numbers! When I added the house numbers to the chart, it became very clear that her husband was the Michael Keri who died on 30 September 1868.

Many records do not even list house numbers, and when they are listed, they are often ignored. That one little puzzle piece made all the difference in determining who this man was. In future weeks I’ll write how I put other puzzle pieces together until I formed a much clearer picture of this man named Michael Keri.


543 is made from three consecutive numbers so it is divisible by 3.

543 is the hypotenuse of the Pythagorean triple 57-540-543. Can you find the greatest common factor of those three numbers?

  • 543 is a composite number.
  • Prime factorization: 543 = 3 x 181
  • The exponents in the prime factorization are 1 and 1. Adding one to each and multiplying we get (1 + 1)(1 + 1) = 2 x 2 = 4. Therefore 543 has exactly 4 factors.
  • Factors of 543: 1, 3, 181, 543
  • Factor pairs: 543 = 1 x 543 or 3 x 181
  • 543 has no square factors that allow its square root to be simplified. √543 ≈ 23.30236
