Championship weekend — the moniker for the convergence of four NCAA lacrosse semifinals and four title games in four days in Foxborough, Massachusetts — will serve as a de facto family reunion for the Kellys.

The Baltimore County-based clan headed by Janet and Francis Kelly Jr. and composed of four sons, 21 grandchildren and four great-grandchildren usually spends a weekend in July on a farm in Easton. But they will meet two months earlier because three members will play inside Gillette Stadium this weekend.

First, junior defenseman Joseph Kim “JK” Kelly and No. 1 seed Cornell (16-1) will face No. 5 seed Penn State (12-4) in a Division I Tournament semifinal Saturday at noon. Then fifth-year senior attackman Daniel Kelly and No. 2 seed Maryland (13-3) will clash with No. 6 seed Syracuse (13-5) in the second semifinal on Saturday at 2:30 p.m.Finally, sophomore midfielder Eyasu Kelly and Dickinson (17-5) will tangle with Tufts (22-0) in a Division III final on Sunday at 7 p.m. More than two dozen family members are expected to show up this weekend.

“It’s awesome,” Daniel said. “It’s something you dream about, playing championship weekend, playing on Memorial Day. To experience this weekend with a lot of family, it’ll be one to remember.”

Added Eyasu: “I still don’t know how it’s real. It feels like a dream.”

The development is just as thrilling for the boys’ fathers.

“At this time last week, we had no idea this was going to be the case,” said Frank Kelly III, father of JK. “So you’re just kind of letting it unfold, and it’s really kind of magical in a way.”

Added David Kelly Sr., Eyasu’s father: “Just very thankful to be a part of this.”

The Kelly family is well-known in the Baltimore area. Janet and Francis Kelly Jr. co-founded Kelly Benefits in 1976 as a small health and life insurance agency. The company has since grown into a national health insurance provider that is run by their four sons: Frank III, chief executive officer; John, chief innovation and strategy officer; David Sr., chief organizational officer; and Bryan, executive vice president.

The family is just as prominent in lacrosse circles. David and Bryan helped North Carolina win NCAA Division I championships in 1986 and 1991, respectively, and John went to three straight Division III title games with Washington College from 1984 to 1986. Bryan is also the head coach at Calvert Hall, which outlasted Spalding for its sixth Maryland Interscholastic Athletic Association A Conference crown.

David’s sons, Patrick and Timmy, and Frank’s son, Stephen, contributed to the Tar Heels capturing a title in 2016, and Bryan’s son, Daniel, won a championship in 2022. The family’s reputation extends beyond the state’s borders.

“They are lacrosse rats,” Cornell coach Connor Buczek quipped. “They are the kings of lacrosse in the Baltimore area, and they bring so much to the game and spread the game and do such a good job as ambassadors of the sport.”

At the start of the season, Daniel, JK, Eyasu, Denver senior midfielder Micaiah “Mic” Kelly, and Georgetown sophomore attackman Joshua “Shuey” Kelly — all of whom played at Calvert Hall for Bryan, father to Daniel and Joshua and uncle to the rest — dreamt of making it to the final weekend of the season. But the Pioneers (7-7) failed to qualify for the postseason, and the Hoyas (12-5) fell to Maryland, 9-6, in an NCAA quarterfinal Sunday at Navy-Marine Corps Memorial Stadium in Annapolis. That even three of the boys are playing on Memorial Day weekend is mind-boggling.

“I don’t think we ever actually talked about it or envisioned it happening,” said JK, who, along with older sister Jackie Lee Kelly, was adopted from South Korea by Gayle and Frank. “But now that it has, it’s very cool.”

All three players and their teams have taken different routes to this stage. Daniel leads the Terps in goals this season with 32, but they were humbled by Ohio State, 14-10, in the Big Ten title game on May 3.

JK has played only four games due to an ankle injury, but Cornell has been overpowering since a 13-12 setback to Penn State on March 8. Eyasu has made just three appearances, while Dickinson overcame a 3-4 start to earn its first trip to the Division III final.

While acknowledging that being relegated to the sideline has been difficult, Eyasu said he was encouraged by a text from cousin Jacob, who won a national championship in 2016 at North Carolina with Eyasu’s older brother duo of Patrick and Timmy.

“He was like, ‘I know it’s tough when you’re not playing, but it’s a great experience. Whether you’re suited up or not, it’s the Final Four. So soak it up. It’s an amazing experience either way. Just hang in there and enjoy everything about it,’” said Eyasu, who, along with younger sister Gibitu “Gibby,” was adopted from Ethiopia by Melissa and David. “That was great to hear.”

Things could get potentially awkward for the family if Cornell and Maryland win on Saturday. That would set up a title-game clash between JK and Daniel.

Although this weekend marks the 30th time the Terps will compete in the Final Four, they have just four NCAA titles. The Big Red have three crowns, but have not triumphed since 1977. But neither player is looking ahead.

“Obviously, it’s in the back of your mind when you think about it,” Daniel said. “But for me, my entire focus right now is on Syracuse. If that happens, that’s awesome, and I’ll give him a hug before the game, and we’ll go from there.”

Said JK: “I don’t really think it will be difficult. I just think it’s something that’s really cool. … All of us want the best for each other, but we also want our teams to win at the end of the day.”

Frank Kelly III, who was a midfielder for Cornell from 1983 to 1986, knows how he would lean.

“(Daniel) can have 10 goals as long as Cornell wins,” he said with a laugh. “But I think we would all be cheering for each other and for the kids.”

The possibility that the Kelly family could leave Foxborough with two more national championships is a scenario the members wholeheartedly embrace.

“That would be incredible,” David said. “Having the Kellys be a part of two national championship teams on the same weekend would be a pretty incredible weekend.”
