Jeb Bush is counting on two familiar names to raise money for his lagging Republican presidential campaign: his brother George W. Bush and his father George H.W. Bush.

George W., who was president from 2001-2009, hosted a fundraiser for his sibling in New York last month, Bloomberg reported, and he hosted a fundraising luncheon for his brother in Rogers, Arkansas on Oct. 2. Dubya also is scheduled to be the featured speaker at pro-Jeb fundraisers in Denver on Oct. 18 and in Washington on Oct. 29.

Dubya and George H.W. Bush, Jeb's father who was president from 1989-1993, are to combine to raise money for Jeb in Houston Oct. 25-26.

There will be a total of 29 fundraising events in October alone involving one or more members of the family including Bush, his wife Columba, their sons Jeb Bush Jr. and George P. Bush, his father and mother, his brother and Dubya's wife Laura, according to the Wall Street Journal. Among former first lady Laura Bush's events are fundraisers in Palm Beach and Winter Park, Florida, on Oct. 7 and 8.

Jeb Bush, the former governor of Florida, says he is his "own man," but he has had trouble emerging from the shadows of his father and brother, especially his brother. Some of Dubya's policies such as the Iraq war were very unpopular when he left office. Dubya also is remembered for the financial meltdown that occurred late in his second term.

Jeb Bush and his allies have raised more than $100 million for "Right to Rise," the political action committee backing his campaign, which is expected to run a huge barrage of television ads in the early primary and caucus states through early 2016.

Some family loyalists are worried because Bush has not delivered impressive performances in the two GOP presidential debates so far and he is fading in the polls after leading in many surveys earlier in 2015. Some polls now place Bush fifth or worse in the crowded GOP field.

But his allies argue that his impressive fundraising ability will keep him in the race despite the poor current ratings in the polls. "If we were frozen with just the resources we have right now, he would still be in the game right to the very end," Bush fundraiser Kenneth Lipper of New York told Fox News Latino.

Other family loyalists concede that Bush needs to keep raising large amounts of money in order to maintain his credibility as a major contender.

That's where his father and brother come in. To raise funds, Jeb wants backing from their networks of supporters. But this automatically calls attention to the family connection and raises the hackles of Republicans who don't want their party to be arranging a Bush dynasty in the White House.
